It is More complicated ISP are required by law enacted in 2022 to see what all a person is looking at and if required they will have over that data to national security agency. So when server like cloudfare encrypt such data ISP are having trouble following the law
That's why I use local ISPs whose primary focus is not deep packet inspection but delivering the speeds they lease from larger ISPs like Airtel and Jio. While they do censor some content, such as TikTok and certain banned websites like Pornhub, they don't block sites like The Pirate Bay or similar ones. Additionally, they don't perform deep packet inspection and provide low latency like 13ms which is pretty good.
Yup i get it from drom local cable service provider and its awesome and he is always available for any issues that arises unlike jio or airtel where its a total mess
This is a very common thing on when Jio is the ISP in my small scale testing They like to block stuff without any rhyme or reason, this is one of the reasons why I always have vps active in azure central india location with ovpn and kasm active so that I can either connect via vpn or ssh or use kasm to launch a private browser instance and do the shit I was trying to do. azure has their own dedicated link from pune to undersea cables, this also has the benefit of being able to get around "govt censorship" as claimed by Jio on movie streaming websites, which are enforced only by Jio for some reason(same websites via airtel are accessable)
Exactly. My university uses Jio as their broadband provider and with University restrictions (which can be bypassed using GoodByeDPI), and Jio on top. Is a very shitty experience.
Same happens to me in Gujarat when I'm trying to access Google Photos in my browser for some reason. It's something particular with the Gujarat ISP maybe
Faced the same issue while I was in Gujarat, WARP seems blocked there and you get Co-location center from France and sometimes UK, Currently now in Maharashtra and WARP working clean here 5ms to Bombay server at the moment.
JIO routing is WAY DIFFERENT than AirTel. I have used them both and perfer AirTel for all traffic and keep JIO as a backup internet. While JIO is per say, not bad, AirTel is still the first choice between the two.
jio's experience is so sh*t, even if i do not have problems like shown in this video, there have been some days where my internet would randomly just become slow, restarting the router, resetting it, restarting devices doesnt fix it.
Yep. Even Google, adguard, openvpn DNS not working. I had to use VPN service that gives VPN DNS options, so i can switch DNS from VPN side when my device set DNS ( google in my case ) dont work.
Check TCP MTU and MSS. Noticed a similar issue connecting to Akamai CDN through some of the large ISPs. Somewhere there is a BGP router or CGNAT router in between having TCP MSS and MTU not configured correctly on the outgoing / incoming network interface, that misconfigured router is not reassembling fragmented TCP packets while leaving it to the next router. Also CDN nowadays puts some sort of packet scrubbing to mitigate TCP reply and fragmentation attacks.

@@siddhantchavan1370I tinkered with some opensource firewalls and Linux routing while setting up my very own network and kubernetes cluster at my home lab. I was curious from my childhood to know the nuts and bolts of the internet ecosystem. So now I have my own network with an Autonomous System, Public IPs and I am a member of RIPE. I started my own experimental research network with my AS203145 and now I expanded it from the cloud to my home.
@@siddhantchavan1370knowing some of the networking stuff and os stuff (socket programming, IPCs, etc.) really helps backend developers to write code for large scalable systems. By profession I am a developer too but I always have this kind of tinkering hobby aside.
From gujarat here, it's an issue with the ISP, specifically YOU Broadband, they use some weird routing and which affects the ping. You need to raise a ticket with your service provider along with the trace route to resolve this issue
Some ISPs have firewalls that cause problems like this. I'll give you an example, I live in Kashmir and here Jio has a firewall in place, it works good for the most part but if i open slack, I'm not able to join meetings sometimes or sometimes media doesn't load. Sometimes even the API's that I'm testing keep failing. But when I switch to my other wifi connection by BSNL, everything works flawlessly.
its nothing to with your location, jio does this everywhere. I have found a workaround by changing the dns server at browser level and everything works fine for the most part, not sure if the above user was using default dns of jio or not.
In my case even google DNS wasnt connecting when using VPN service, i had to find VPN provider that also had option to choose DNS ( dns from VPN side ).
@@pulkitsukhija I would not be surprised, WARP has been a part of their zero trust offering, so having it on another app is expected. AFA this situation goes, its only removed from indian play store and is still accessible via pre-installed APKs or any wireguard client (which might change as WARP switches to their new protocol). This along with countless other VPNs leaving india just points to the obvious. Although I would love to read the article if its something I am totally clueless on.
ISP's in India makes VPN connections extremely slow, also some sites keep breaking with a particular ISP everytime, but works with another ISP... It's makes internet experience pathetic sometimes...
you can also ask the user to check the cf server location by asking him to go learn.coders..../cdn-cgi/trace also if you use warp+ then speeds aren't affected it's some heavy messup with Airtel, Jio routing
I also have this issue, I used to cloudflare regularly before but now the internet speed of my device is significantly slower when use cloudfare. Thats why I left cloudflare.
@@parthbhardwaj4279 hey but what is the usecase of this cloudflare vpn in your case..as in using unreachable websites or anonymity or something else entirely ?
The best troubleshooting should be done is connect him with his mobile network which has different ISP because ISP routers uses BGP protocol to connect to the hops and different isp use different types of QOS mechanism to priotize the traffic, If you look clearly your html and css images are loading fast but when it comes to video it sucks but they are having different QOS mechanisms.
it's probably somehow ISP problem. whenever i update my system threw via my Jio 5G network it's provide 1 KB to 100 KB speed but in youtube i can watch video & stream 1080p60, when i change to Vi 4G network it's speed like 500 KB to 2 or 4 MB speed sometimes it's like 6 MB idk why ?
For ISP I recommend having two different connections. I understand that getting two fiber connections might not be possible for small scale but having at least a second connection dedicated to the server. Considering that ISP fiber connection provides 90% uptime average in india so having a second low cost setup will be helpful and a Different ISP means a different routing network which will be helpful in these situations.
A simple restarting all the network stuff will be helpful for resetting network route to best connectivity(I had faced similar problems in the past and this was the simplest thing I personally doing for better connectivity)
Our isp's just block cloudflare subdomains because some people use it as bug host and this specific problem occurs more in jio than airtel and than maybe vi.
@pulkitsukhija Yeah, or maybe 1. The websites aren't accepting traffic from some countries. 2. Routers are hacked by some TR 069 exploit and that triggering anti DDoS mechanism. (It's very easy with D-Link, i suggest you to watch Low Level Learning video about this)
Since the user was able to access the same website using different internet medium, it is most likely MTU issue. Try changing the interface's (e.g eth0) MTU to values like 1300, 1250, 1200 or lower and play with different values.
Very true, this specific issue is with the JIO fiber. They like to throttle almost every data packet. I have extensively tested with 2 different Jio Fiber connections and observe exact same issue. I switched to local ISP and it is so much better.
I used to host my own VPN at some Mumbai based VPS and that used to solve all my routine based latency issues for me. Because the ISPs would "provide" good speed, but in reality it would have terrible routing and most sites would be extremely slow.
ISP issue definitely. I had similar issue where Netflix and some parts of Amazon websites (prime, aws) were not loading but everything else is working fine. Contacting my wifi provider resolved it, they took my router and changed some internal id and it started working fine.
If it's a local isp then that should be the problem IMO. Coz I have experienced like this with Google meet while attending a class. In my case same was happening after switching to mobile data the issue was not happening. It happens with specific website or service.
I have having this problem with jio 4g for around more than a year, some apps and websites just didn't work with jio, earlier i used to solve this problem by turning on cloud flare, today i was booking a cab, the speed was slow, then turned on cloudflare warp, nothing worked, checked youtube it was working fine, whenever i recharged jio i faced problem with some or other site always, the other sim i have is Vi, which works perfectly fine for all websites and apps
Had similar kinds of issues multiple times some of our website users not able to play videos from Vimeo cdn . I think it also affects Google sign-in for some people
This appears to be a throttling or peering issue between the specific ISP and the CDN. It could also result from data inspection or filtering on the CDN's side or the ISP's network, causing delays. While using a custom route table might offer a solution, it would involve significant effort and fine-tuning to define effective custom routes.
It is the ISP issue with peering to one of the Cloudflare POPs. If the ISP is one of the tier3 providers then the user has to get along with the ISP to get it resolved. This would also mean there are multiple people in the area/zone which are facing similar issue. If its tier2 ISP, Cloudflare may even help you resolving this issue when you are one of the paying customers of CF. When the user is using Mobile hotspot the ISP is changed hence the Routing. You, Codersgyan and CF cannot much do in case of tier3 ISP. Though, Tier3 are just resellers of B/W from tier2 so most like the issue might persist in between tier3 and tier2.
As far as I've noticed, ISPs using jio's DNS systems cause issues with cloudflare. I noticed 3 ISPs with this and 2 without and the issue happened as I described
If removing cloudflare fixes it then it's definitely cloudflare problem. If route has similar or same nodes, then it could be a problem with one of those nodes. If nodes are changing, then see what node remains constant to narrow down the faulty system.
Mere isp ne mera hi website block kar diya tha mai socha mera website down kyu ho Raha hai pahale hosting dekha sab running condition me tha phir VPS check kiya wo bhi running me tha phir samjh gaya ye mere ISP ka kand hai..
I thought it was just me but having routing issues for more than 4 months now !! its frustrating as my local ISP doesn't know about these errors and label them as "UNIQUE ERRORS" !!
I had a similar issue with my WordPress site I was the only one who was not able to reach the site via wifi. I checked the DNS entries and found that they hadn't refreshed the DNS config which was changed 2 days prior
Still happens with me a lot in Gurgaon and punjab, while playing call of duty game only. Game works fine on sim card, but on airtel wifi never starts. As a solution i start game on sim and after login switch to wifi, then works
I had the same issue with Jio, one reason I switched out from Jio to a different ISP. Only issue I could diagnose with Jio is that they are using IPv6 only without IPv4.
The Cloudflare and Indian ISP part is heavily discussed. Cloudflare is faster if you're using their premium services and not just free CDN, Argo being one of them. Big ISP wanted cloudflare to pay for the traffic so to balance cost unless the domain is premium they don't use premium peering for the most part. It's a Cloudflare and ISP issue.. I'd suggest move to Bunny CDN if DNS and CDN is all you want.
It's not the ISPs, it's the cloudflare which has very bad peering with Indian ISPs. Most of the time you will end up connecting route node outside India and thus the packets route across the glove before it reaches you. Their anycast often results into flooding origin server if timeout happens. There's only one solution : All users must push CF to fix their peering with ISPs. There's some bad routing involved and node selection algorithm is performing quite bad. There might be another reason where they are deliberately doing it to extract data, most selected nodes are strategic locations where data processing laws are not strict so there is another angle to why CF might be doing it. There's surveillance possibility involved by non Indian companies and that's a real issue.
It happens with JIO and with most VPNs. JIO is selectively blocking many VPN services. The best you can do is switch from JIO or try different VPNs that work for you. In my case, it was definitely a VPN problem because it was refusing to connect to Google DNS, but the DNS from the VPN was working fine, though too slow. It is 100% the ISP, and it is definitely not a user problem that JIO's untrained customer care does not understand.
I would also try changing the dns to any good private dns (nextdns or cloudflare dns) , few isps use their nonsense dns resolvers which screws up routing . i would recommend that Private Dns must be enabled at both router level and device levels hope the issue gets resolved with this
DNS is likely not the issue here. DNS only does domain name to IP address conversion which happens just fine. The problem is the data transfer is very very slow which is not the responsibility of DNS
TLDR, before I switch to my Unbound DNS. My outlook web was working. Did some test Unbound DNS and Cloudflare DNS is resolving a different address to Microsoft cdn. Unbound is giving me an address with bad routing I guess. Some reading also point me to EDNS not being supported back then for Unbound, thus it is giving me an address with bad routes.
I'm not sure about this, but this happened to me on multiple instances where switching the network works, or changing the DNS works. Incident 1: Sanity CMS dashboard kept loading Contentful homepage kept loading Resolved by changing dns Incident 2: I coded and deployed a website and assigned a custom domain (godaddy), the website was live on the domain as viewed from other networks, but not particularly my WiFi. I dug into this behaviour and back then I came to know that either WiFi routers or somewhere in the hop stream devices cache the route. The config could have changed somewhere and the cache didn't revalidate yet. It has a fixed refresh time and it works once that happens. This incident mentioned in the video closely resembles my experiences.
@@codedamn should try to traceroute on the affected pc and try pinging ips which could tell u that it is a dns problem or i think ur right that it might not be a dns problem, and ip while pinging that has the highest wait time is the culprit then u can investigate further
That's why I use Local ISP with Asus Router. No censorship & Inbuilt Asus AI, VPN & Firewall Security. JIO & AIRTEL provide cheap Chinese XPON, Switch & Router & I feel more comfortable when my DATA is in Taiwanese hand 😂
@yoppindia Any model starting from AX 1800 has those security features, higher you go, the better. All the mentioned security features require no subscription, Asus provides them for free , even the updates.
I am using Airtel Air Fiber connection (100Mbps) and when I use my company VPN the speed drops to few Kbps. The issue is with the Airtel Air Fiber only. I didn't had this issue with Jio Air Fiber, Airtel Fiber connection nor mobile data(VI). I am unable to work with my work VPN.
I faced the same issue and fixed it by using IPv4. The issue mainly occurs on the JIO network, where the JIO IPv6 network connects very slowly to the Cloudflare server. I did a lot of digging, and to fix it, I used an external router with a dynamic setup and allowed only the IPv4 interface.
I also experience this problem, sometimes my wifi broadband is unable to open some sites or take long time, but when connecting through mobile data, that open quickly.
After having many features blocked by JIO on my router after the recent firmware update, I am currently in the search of a good ISP that only gives the internet and does not have control over my router.
When I was in Gujarat, I used Jio fiber and could not for the life of me use cloudflare warp. I used to use warp to get better ping in games to singapore servers and once i moved to jio fiber it stopped working. So yeah youre right when you say the ISPs are not properly routing traffic.
he needs to call ISP and ask to redirect his cloudflare traffics to another route, some bgp is messed up in his current routing for sure. btw you can use mtr to get realtime ping status on each hops the traffic is using and point out the exact faulty hop.
Like @DebdutBiswasOnline mentioned in another comment, a router at one of the hops could be messing with TCP packets. If that's the case then I'm not sure it's really fixable (maybe with the client's ISP's customer support, but that's a long shot). Anyways, have you tried to check what kind of traffic is being dropped by the router? Try running a traceroute from the client to the Cloudflare's IP. I think the traceroute utility can use non-ICMP packets to trace as well, so that might help in spotting the router and figuring out its behavior. Also, the client likely uses a dynamic IP. So maybe the traffic routes will also change with the change in IP, which would "solve" the issue. Do post a follow-up if there's new information!
Ive felt it with mobile internet as well. Jio Vi etc . Sometimes site won't open. Sometimes they lag s lot. Sometimes hotspot to laptop doesnt opens the site but doing usb tethering does the job. Some govt site are very hard to open with this , even vpn does a good job opening it through the same ISP. Could be their ignorance, basically maybe they dont wanna do a lot of work to rectify it. Besides a common man doesnt pays much attention to these , they just think internet is bad today ( just as always ; jio has normalised it too much by giving poor internet speed)
It is IPv6 . Cloudflare backend is purely IPv6, where as this ISP may not be natively giving IPv6 addresses, or they may not have a IPv6 Wrapper in the gateway. You can also verify and confirm this by disabling IPv6 in the laptop/workstation.
Since Cloudflare has nearby servers based on locations, could it be that the Cloudflare server that people from Gujarat are using has a problem and not from Bangalore? That would explain why WARP slows down things for him.
It is the Ip's problem. IPv4 vs IPv6. Problem here is when they don't have ipv4 in that location at that moment they assign only ipv6 ( i am talking about cloudflare ) and at that moment when our local isp do not enable IPV6 that is obvious because IPv6 require new hardware, we face those issue connecting ipv6 only website. He do connect successfully connected when he switch to mobile because mobile ISP always give ipv4 and ipv6 ip's.
1. Have you told him to reset their router setting , may be there is some rules and routing set by him or someone 2. Have he tried on different devices or different pc/laptop. 3. He can also see if there is custom dns set by him or their is default dns may be try to change it to some other dns services. 4. (If not sure about the connection and pc setting ) I would route my wifi through mobile acting as repeater having both wifi and hotspot on,mobile wifi is connected to router and pc to mobile hospot. Just to check flakkyness of the connection settings.
@@xtan-io I have seen whole video, and I am not that free to just write random thing. It personally happended to my user, He added certain rules and script on router to block ad and trackers.
I don't think it's possible to use phone as a repeater. Once it's connected to wifi, how can it be a router at the same time. That's a hardware limitation.
it is crazy how our eyes light up when the problem is far our reach, and you know that there is lots of knowledge to be achieved if you get to solve it! reasons i love software eng!!
Understand ur problem this happen bcos of cloudfare as they are using automated tool to identify the optimal routing path. Reverse traffic sending towards the ISP. Many time the path choosen are not optimal and need alternate path but automated tool understand this as best path bcoz of all the parameters configured are found ok... which may not be the best. And still keep sending traffic on the wrost path.
The same problem we faced in Gurgaon, our website was inaccessible on the Vodafone mobile network because API calls were failing, and our backend was hosted on AWS. When we checked other AWS-hosted websites like Airbnb they were also inaccessible on the Vodafone network.
Listining to this, i can say i have same issue from the last month, it comes and goes, sounds same to me even your point that switching from wifi to mobile data immediately makes everything fine
A similiar yet different problem for me, The gifs from tenor in some apps like discord or whatsapp doesn't load up on my Wifi but works perfectly fine when, Wifi with any VPN/cloudflare or mobile data.
Same issue happens while online gaming as well. I face issues like- 1) Random packet losses and jitters even though i am on wired connection (I dont face ths issue anymore but i am sure it was ISP related) 2) While playing counter strike on mumbai server (i live in mimbai) the game for some reason routes my network from chennai and back to mumbai which makes no sense at all. I face this issue sometimes only but its annoying when it happens as it causes bit higher ping.
This happens on the reliance internet. Not just gigafiber but with mobile internet as well. My research also directed me towards disabling the ipv6 in cloudflare, but being a free user I could not do it.
We are also facing a similar issue with cloudflare, but we found that the issue was only faced by the user with Jio network connection and not by the users using other ISPs. I am from Gujarat, by the way.
I use a Local ISP(In Mumbai) and a airtel hotspot for backup(incase of a freak power cut or something). The local isp has subleased directly from Tata Telecom(owners of undersea cables and infrastructure in india) and everything works well there for cloudflare warp or even anything else. Whereas with airtel even seeders seem to be dropping while torrenting,even the inbuilt search plugin in qbittorrent does not work over airtel(100% dpi) and some cloudflare websites(without warp) sometimes have a higher latency and misses(routing to a diff ip for the content) either it could be a cache miss on cloudflares end(this could be possible) or airtel is doing DPI in between. I suspect the later because even popular websites served by cloudflare(which wont have a cdn cache miss) sometimes run oodly slow. My Local isp does not have this problem with the same website on a different computer/laptop/phone(deducing this to a non-cache miss at the cdn level) . Location is Mumbai BTW.
This is such a nice video, so much important information is presented in a easy to understand method in under 15 minutes. also thanks for showing the real problem users face everyday
This happens with me a lot. I think there is some sort of caching happening ISPs end. Because some pages would not work at first but after some time if I retry they would somewhat start working.
Very same thing is true with Flight simulator we are building in Ahmedabad.. Its ISP fault. We have changed multiple routers, modems everything in between!
I guess it's basically the fault of the internet provider because it happens to me sometimes. What happens is that the route the packet is taking becomes lengthy (I don't know the reason, maybe a bad route selection algorithm)
I use airtel and I too noticed this problem when accessing Udemy. My neighbour using a local ISP gets a flawless access to this site and every others, I'm planning to switch to that soon. Also the customer service provided by airtel or jio is subpar.
This is the reason why i switched to aws instead of using cloudflare rds. I was using jio and spent the whole day debugging code, only to discover that using a vpn solved my problem. Then i switched to aws even though it might be more expensive. No hiccups from there.
I think the problem is ISP sharing multiple connections on a single public IPv4 (I know that ACT does this and would be similar for small scale ISPs) and as a result, Cloudflare can throttle requests thinking the public IP as a spammer (since multiple customers have same public IP)
This is so weird that I'm having this exact problem, but with entirely different ISPs and products. I'm trying to connect to a work VPN hosted in another country. Trying to connect to this VPN and using the remote system while on a residential ISP, it'll always route me through a server that has consistently high ping (230-300ms). I have to disconnect and connect multiple times in order to force myself to connect using a faster path. However, the moment I switch to a different ISP, the problem vanishes and I'm able to connect 100% of the time with pings around 100-110ms. Funnily enough, this residential ISP problem only occurs in the town I live, and whenever I move to a different city and use the same ISP from there, the problem does not occur.
i have same problem with my server, the issue is from ISP, it not able to serve some site or ip for few secs, it generally happens with BSNL, Airtel and GTPL (spl in gujarat). At that time speed test and youtube will be working fine.
This issue has increased significantly in JIO after they implemented the CG-NAT. On top of that, changing DNS doesn’t work with them, it’s not stable. There are high chances that the issue will be resolved when the IP gets refreshed ( In there technical teams words ). Airtel, Excitel performs really good with minimal DNS change.
ISPs dont assign public IP to individual connection. All connections in a building are on Private IP behind a single public IP address. So if there’s any issue with that IP routing than we are simply f’ed. Airtel’s implementation of this CG-NAT is far better than JIO.
I am from Gujarat, we are using on premise hosted Application (Web and Mobile). As per the observation mainly the Jio Users are facing this issue. Rest all users can access the application with proper speed.
Looking at this without having the opportunity to run traceroute and pinging individual nodes to identify the latency and packet drop, I would say the issue is probably in one of the exit nodes which route the traffic. I'm not an expert in Network Architecture so take it with a grain of salt, I'm hypothesizing that the exit nodes might have some throttling based on route and cloud flare being widely used might be getting throttled or the resources at the exit nodes might be bad. These are owned by TRAI if I'm not wrong or in some cases leased to bigger ISPs by TRAI for maintaining the infra. Usually the work around is to build redundancy but not sure how effective these are. One question I would ask the customer is if they're seeing any increase in performance during non-peak hours like middle of night to rule this hypothesis out.
The issue seems to be because of the contention at peering facilities like Internet Exchange . We were facing same issue and we also have bilateral peering with cloudflare. The problem was fixed after reporting to the Internet exchange. There was also a partial routing issue at some locations which cloudflare had published.

I was curious from my childhood to know the nuts and bolts of the internet ecosystem. So now I have my own network with an Autonomous System, Public IPs and I am a member of RIPE. I started my own experimental research network with my AS203145 and now I expanded it from the cloud to my home.
@@siddhantchavan1370knowing some of the networking stuff and os stuff (socket programming, IPCs, etc.) really helps backend developers to write code for large scalable systems. By profession I am a developer too but I always have this kind of tinkering hobby aside.
From gujarat here, it's an issue with the ISP, specifically YOU Broadband, they use some weird routing and which affects the ping. You need to raise a ticket with your service provider along with the trace route to resolve this issue
i also observed an similar issue in chennai on Wednesday with BSNL Fiber, it was resolved after 3-4 hours
Some ISPs have firewalls that cause problems like this. I'll give you an example, I live in Kashmir and here Jio has a firewall in place, it works good for the most part but if i open slack, I'm not able to join meetings sometimes or sometimes media doesn't load. Sometimes even the API's that I'm testing keep failing. But when I switch to my other wifi connection by BSNL, everything works flawlessly.
its nothing to with your location, jio does this everywhere. I have found a workaround by changing the dns server at browser level and everything works fine for the most part, not sure if the above user was using default dns of jio or not.
In my case even google DNS wasnt connecting when using VPN service, i had to find VPN provider that also had option to choose DNS ( dns from VPN side ).
WARP has been removed from playstore and appstore, following a govn takedown request. Smells like something is cooking.
Yeaaaah dude I was like wth why can't I find it
holy you're right.
Not true, it was not due to that, they have rolled out another app which has warp in it, I read on their website
@@pulkitsukhija I would not be surprised, WARP has been a part of their zero trust offering, so having it on another app is expected. AFA this situation goes, its only removed from indian play store and is still accessible via pre-installed APKs or any wireguard client (which might change as WARP switches to their new protocol). This along with countless other VPNs leaving india just points to the obvious. Although I would love to read the article if its something I am totally clueless on.
ISP's in India makes VPN connections extremely slow, also some sites keep breaking with a particular ISP everytime, but works with another ISP... It's makes internet experience pathetic sometimes...
damn bro thnx a lot for covering this , ive been affected by same.
also this issue doesn't exist on BSNL ☠️
you can also ask the user to check the cf server location
by asking him to go
learn.coders..../cdn-cgi/trace
also if you use warp+ then speeds aren't affected
it's some heavy messup with Airtel, Jio routing
Why not on bsnl@@user8921
I also have this issue, I used to cloudflare regularly before but now the internet speed of my device is significantly slower when use cloudfare.
Thats why I left cloudflare.
By cloudflare, I mean cloudflare warp vpn.
@@parthbhardwaj4279 hey but what is the usecase of this cloudflare vpn in your case..as in using unreachable websites or anonymity or something else entirely
?
what's your isp?
@mr.lastchance Airtel fibre
@@parthbhardwaj4279vpn is a different case
The best troubleshooting should be done is connect him with his mobile network which has different ISP because ISP routers uses BGP protocol to connect to the hops and different isp use different types of QOS mechanism to priotize the traffic, If you look clearly your html and css images are loading fast but when it comes to video it sucks but they are having different QOS mechanisms.
it's probably somehow ISP problem. whenever i update my system threw via my Jio 5G network it's provide 1 KB to 100 KB speed but in youtube i can watch video & stream 1080p60, when i change to Vi 4G network it's speed like 500 KB to 2 or 4 MB speed sometimes it's like 6 MB idk why ?
Your knowledge and problem solving skills are amazing dawg
For ISP I recommend having two different connections. I understand that getting two fiber connections might not be possible for small scale but having at least a second connection dedicated to the server. Considering that ISP fiber connection provides 90% uptime average in india so having a second low cost setup will be helpful and a Different ISP means a different routing network which will be helpful in these situations.
A simple restarting all the network stuff will be helpful for resetting network route to best connectivity(I had faced similar problems in the past and this was the simplest thing I personally doing for better connectivity)
Or maybe just go a friend who uses a different ISP
Our isp's just block cloudflare subdomains because some people use it as bug host and this specific problem occurs more in jio than airtel and than maybe vi.
what is bug host?
Likely Cloudflare DDoS protection from abuse from that ISP's ip range. Reason why those pages loaded is because of cache this user had, maybe?
Possible, cloudflare was definitely blocking some ISP's a while back for the same reason
@pulkitsukhija Yeah, or maybe 1. The websites aren't accepting traffic from some countries.
2. Routers are hacked by some TR 069 exploit and that triggering anti DDoS mechanism. (It's very easy with D-Link, i suggest you to watch Low Level Learning video about this)
Since the user was able to access the same website using different internet medium, it is most likely MTU issue. Try changing the interface's (e.g eth0) MTU to values like 1300, 1250, 1200 or lower and play with different values.
Once I had a slow connection to vercwl hosted sites
Complained to my ISP
They said they cleared DHCP pool and then it started working fine
lol
Very true, this specific issue is with the JIO fiber. They like to throttle almost every data packet. I have extensively tested with 2 different Jio Fiber connections and observe exact same issue.
I switched to local ISP and it is so much better.
I used to host my own VPN at some Mumbai based VPS and that used to solve all my routine based latency issues for me.
Because the ISPs would "provide" good speed, but in reality it would have terrible routing and most sites would be extremely slow.
ISP issue definitely. I had similar issue where Netflix and some parts of Amazon websites (prime, aws) were not loading but everything else is working fine. Contacting my wifi provider resolved it, they took my router and changed some internal id and it started working fine.
Most discord pfp doesn't show up when I'm using my Wi-Fi. I use nextDNS now and it fixes the issue.
i use opendns and after that no censorship issue whatso ever
I had similar problems when I used airtel as network provider, and when I used other ISPs it worked fine for me.
If it's a local isp then that should be the problem IMO. Coz I have experienced like this with Google meet while attending a class. In my case same was happening after switching to mobile data the issue was not happening. It happens with specific website or service.
I have having this problem with jio 4g for around more than a year, some apps and websites just didn't work with jio, earlier i used to solve this problem by turning on cloud flare, today i was booking a cab, the speed was slow, then turned on cloudflare warp, nothing worked, checked youtube it was working fine, whenever i recharged jio i faced problem with some or other site always, the other sim i have is Vi, which works perfectly fine for all websites and apps
Had similar kinds of issues multiple times some of our website users not able to play videos from Vimeo cdn .
I think it also affects Google sign-in for some people
I had an ACT static ip and I was hosting a site and the funniest thing is only other ACT users couldn't access my site!!!
Very fishy
This appears to be a throttling or peering issue between the specific ISP and the CDN. It could also result from data inspection or filtering on the CDN's side or the ISP's network, causing delays. While using a custom route table might offer a solution, it would involve significant effort and fine-tuning to define effective custom routes.
It is the ISP issue with peering to one of the Cloudflare POPs. If the ISP is one of the tier3 providers then the user has to get along with the ISP to get it resolved. This would also mean there are multiple people in the area/zone which are facing similar issue. If its tier2 ISP, Cloudflare may even help you resolving this issue when you are one of the paying customers of CF. When the user is using Mobile hotspot the ISP is changed hence the Routing. You, Codersgyan and CF cannot much do in case of tier3 ISP. Though, Tier3 are just resellers of B/W from tier2 so most like the issue might persist in between tier3 and tier2.
As far as I've noticed, ISPs using jio's DNS systems cause issues with cloudflare. I noticed 3 ISPs with this and 2 without and the issue happened as I described
If removing cloudflare fixes it then it's definitely cloudflare problem. If route has similar or same nodes, then it could be a problem with one of those nodes. If nodes are changing, then see what node remains constant to narrow down the faulty system.
Mere isp ne mera hi website block kar diya tha mai socha mera website down kyu ho Raha hai pahale hosting dekha sab running condition me tha phir VPS check kiya wo bhi running me tha phir samjh gaya ye mere ISP ka kand hai..
unko boblo unblok kare
Thats why I stick to local smaller ISPs. They tend to not block anything.
I thought it was just me but having routing issues for more than 4 months now !! its frustrating as my local ISP doesn't know about these errors and label them as "UNIQUE ERRORS" !!
This is because of the double NAT system used by big Indian ISPs like jio and airtel.
I sometimes face this issue where instagram(and some other sites) slow down randomly which gets fixed by changing the DNS servers
I had a similar issue with my WordPress site I was the only one who was not able to reach the site via wifi. I checked the DNS entries and found that they hadn't refreshed the DNS config which was changed 2 days prior
Still happens with me a lot in Gurgaon and punjab, while playing call of duty game only. Game works fine on sim card, but on airtel wifi never starts. As a solution i start game on sim and after login switch to wifi, then works
It's JIO issue, i am also having the same issue with my app.
fact .. yes this is JIO issue ..
i had issues with jio for GitHub as well sometimes
yeah i also had issue.
I had the same issue with Jio, one reason I switched out from Jio to a different ISP. Only issue I could diagnose with Jio is that they are using IPv6 only without IPv4.
The Cloudflare and Indian ISP part is heavily discussed.
Cloudflare is faster if you're using their premium services and not just free CDN, Argo being one of them. Big ISP wanted cloudflare to pay for the traffic so to balance cost unless the domain is premium they don't use premium peering for the most part.
It's a Cloudflare and ISP issue.. I'd suggest move to Bunny CDN if DNS and CDN is all you want.
It's not the ISPs, it's the cloudflare which has very bad peering with Indian ISPs. Most of the time you will end up connecting route node outside India and thus the packets route across the glove before it reaches you.
Their anycast often results into flooding origin server if timeout happens.
There's only one solution : All users must push CF to fix their peering with ISPs. There's some bad routing involved and node selection algorithm is performing quite bad.
There might be another reason where they are deliberately doing it to extract data, most selected nodes are strategic locations where data processing laws are not strict so there is another angle to why CF might be doing it. There's surveillance possibility involved by non Indian companies and that's a real issue.
It happens with JIO and with most VPNs. JIO is selectively blocking many VPN services. The best you can do is switch from JIO or try different VPNs that work for you. In my case, it was definitely a VPN problem because it was refusing to connect to Google DNS, but the DNS from the VPN was working fine, though too slow. It is 100% the ISP, and it is definitely not a user problem that JIO's untrained customer care does not understand.
I would also try changing the dns to any good private dns (nextdns or cloudflare dns) , few isps use their nonsense dns resolvers which screws up routing .
i would recommend that Private Dns must be enabled at both router level and device levels
hope the issue gets resolved with this
DNS is likely not the issue here. DNS only does domain name to IP address conversion which happens just fine. The problem is the data transfer is very very slow which is not the responsibility of DNS
I second this. Similar thing in the video has happened to me as well.
Switch to Cloudflare dns and it was working!
TLDR, before I switch to my Unbound DNS. My outlook web was working.
Did some test Unbound DNS and Cloudflare DNS is resolving a different address to Microsoft cdn.
Unbound is giving me an address with bad routing I guess. Some reading also point me to EDNS not being supported back then for Unbound, thus it is giving me an address with bad routes.
I'm not sure about this, but this happened to me on multiple instances where switching the network works, or changing the DNS works.
Incident 1:
Sanity CMS dashboard kept loading
Contentful homepage kept loading
Resolved by changing dns
Incident 2:
I coded and deployed a website and assigned a custom domain (godaddy), the website was live on the domain as viewed from other networks, but not particularly my WiFi.
I dug into this behaviour and back then I came to know that either WiFi routers or somewhere in the hop stream devices cache the route. The config could have changed somewhere and the cache didn't revalidate yet. It has a fixed refresh time and it works once that happens.
This incident mentioned in the video closely resembles my experiences.
@@codedamn should try to traceroute on the affected pc and try pinging ips which could tell u that it is a dns problem or i think ur right that it might not be a dns problem, and ip while pinging that has the highest wait time is the culprit then u can investigate further
That's why I use Local ISP with Asus Router. No censorship & Inbuilt Asus AI, VPN & Firewall Security. JIO & AIRTEL provide cheap Chinese XPON, Switch & Router & I feel more comfortable when my DATA is in Taiwanese hand 😂
what is the router model, is there monthly fees?
@yoppindia Any model starting from AX 1800 has those security features, higher you go, the better. All the mentioned security features require no subscription, Asus provides them for free , even the updates.
@ekkabipin2993 hmm thanks
I am using Airtel Air Fiber connection (100Mbps) and when I use my company VPN the speed drops to few Kbps. The issue is with the Airtel Air Fiber only. I didn't had this issue with Jio Air Fiber, Airtel Fiber connection nor mobile data(VI). I am unable to work with my work VPN.
It's govt blocking vpns lol
This is very common issue i have been facing, being a SaaS provider, nothing hurts us more than this. I hope something can be done in this case.
I faced the same issue and fixed it by using IPv4. The issue mainly occurs on the JIO network, where the JIO IPv6 network connects very slowly to the Cloudflare server. I did a lot of digging, and to fix it, I used an external router with a dynamic setup and allowed only the IPv4 interface.
I also experience this problem, sometimes my wifi broadband is unable to open some sites or take long time, but when connecting through mobile data, that open quickly.
After having many features blocked by JIO on my router after the recent firmware update, I am currently in the search of a good ISP that only gives the internet and does not have control over my router.
When I was in Gujarat, I used Jio fiber and could not for the life of me use cloudflare warp. I used to use warp to get better ping in games to singapore servers and once i moved to jio fiber it stopped working. So yeah youre right when you say the ISPs are not properly routing traffic.
he needs to call ISP and ask to redirect his cloudflare traffics to another route, some bgp is messed up in his current routing for sure. btw you can use mtr to get realtime ping status on each hops the traffic is using and point out the exact faulty hop.
Like @DebdutBiswasOnline mentioned in another comment, a router at one of the hops could be messing with TCP packets. If that's the case then I'm not sure it's really fixable (maybe with the client's ISP's customer support, but that's a long shot).
Anyways, have you tried to check what kind of traffic is being dropped by the router? Try running a traceroute from the client to the Cloudflare's IP. I think the traceroute utility can use non-ICMP packets to trace as well, so that might help in spotting the router and figuring out its behavior.
Also, the client likely uses a dynamic IP. So maybe the traffic routes will also change with the change in IP, which would "solve" the issue.
Do post a follow-up if there's new information!
Ive felt it with mobile internet as well. Jio Vi etc . Sometimes site won't open. Sometimes they lag s lot. Sometimes hotspot to laptop doesnt opens the site but doing usb tethering does the job. Some govt site are very hard to open with this , even vpn does a good job opening it through the same ISP.
Could be their ignorance, basically maybe they dont wanna do a lot of work to rectify it. Besides a common man doesnt pays much attention to these , they just think internet is bad today ( just as always ; jio has normalised it too much by giving poor internet speed)
It is IPv6 . Cloudflare backend is purely IPv6, where as this ISP may not be natively giving IPv6 addresses, or they may not have a IPv6 Wrapper in the gateway.
You can also verify and confirm this by disabling IPv6 in the laptop/workstation.
Juat yesterday, i disconnected the antennas inside the JioFiber Router.
No way to turn off inbuilt wifi after the Nov Firmware Update.
Exactly, I feel ISP is doing something to make us slow , also when we vpn instant website loads
Since Cloudflare has nearby servers based on locations, could it be that the Cloudflare server that people from Gujarat are using has a problem and not from Bangalore? That would explain why WARP slows down things for him.
It is the Ip's problem. IPv4 vs IPv6. Problem here is when they don't have ipv4 in that location at that moment they assign only ipv6 ( i am talking about cloudflare ) and at that moment when our local isp do not enable IPV6 that is obvious because IPv6 require new hardware, we face those issue connecting ipv6 only website. He do connect successfully connected when he switch to mobile because mobile ISP always give ipv4 and ipv6 ip's.
1. Have you told him to reset their router setting , may be there is some rules and routing set by him or someone
2. Have he tried on different devices or different pc/laptop.
3. He can also see if there is custom dns set by him or their is default dns may be try to change it to some other dns services.
4. (If not sure about the connection and pc setting ) I would route my wifi through mobile acting as repeater having both wifi and hotspot on,mobile wifi is connected to router and pc to mobile hospot. Just to check flakkyness of the connection settings.
The User registration info is not hard coded to the router, if we reset we won't get a network unless we login with some credentials.
watch the full video bro, he covered everything you've mentioned.
@@xtan-io I have seen whole video, and I am not that free to just write random thing.
It personally happended to my user, He added certain rules and script on router to block ad and trackers.
@@xtan-io There is a thing called TR069 , it auto configs the router with the users info if you reset it.
I don't think it's possible to use phone as a repeater. Once it's connected to wifi, how can it be a router at the same time. That's a hardware limitation.
Very articulately explained!
it is crazy how our eyes light up when the problem is far our reach, and you know that there is lots of knowledge to be achieved if you get to solve it! reasons i love software eng!!
Understand ur problem this happen bcos of cloudfare as they are using automated tool to identify the optimal routing path. Reverse traffic sending towards the ISP. Many time the path choosen are not optimal and need alternate path but automated tool understand this as best path bcoz of all the parameters configured are found ok... which may not be the best. And still keep sending traffic on the wrost path.
The same problem we faced in Gurgaon, our website was inaccessible on the Vodafone mobile network because API calls were failing, and our backend was hosted on AWS. When we checked other AWS-hosted websites like Airbnb they were also inaccessible on the Vodafone network.
Listining to this, i can say i have same issue from the last month, it comes and goes, sounds same to me even your point that switching from wifi to mobile data immediately makes everything fine
Did your customer try restarting the router? . Regards, ISP Customer care
A similiar yet different problem for me,
The gifs from tenor in some apps like discord or whatsapp doesn't load up on my Wifi but works perfectly fine when, Wifi with any VPN/cloudflare or mobile data.
Same issue happens while online gaming as well. I face issues like-
1) Random packet losses and jitters even though i am on wired connection (I dont face ths issue anymore but i am sure it was ISP related)
2) While playing counter strike on mumbai server (i live in mimbai) the game for some reason routes my network from chennai and back to mumbai which makes no sense at all. I face this issue sometimes only but its annoying when it happens as it causes bit higher ping.
This happens on the reliance internet. Not just gigafiber but with mobile internet as well. My research also directed me towards disabling the ipv6 in cloudflare, but being a free user I could not do it.
jio uses ipv6 connection how can u disable it ? if u disable it then u r internet will not work i guess they provide u ipv4 but on WAN level
Can we also please go back and optimize websites to easily load up in 2-10 mbps connections too?
We are also facing a similar issue with cloudflare, but we found that the issue was only faced by the user with Jio network connection and not by the users using other ISPs. I am from Gujarat, by the way.
Using quad 9 dns resolves a lot of issues lol
I see significant drop in speed with cloudfare warp enabled.
I use a Local ISP(In Mumbai) and a airtel hotspot for backup(incase of a freak power cut or something). The local isp has subleased directly from Tata Telecom(owners of undersea cables and infrastructure in india) and everything works well there for cloudflare warp or even anything else. Whereas with airtel even seeders seem to be dropping while torrenting,even the inbuilt search plugin in qbittorrent does not work over airtel(100% dpi) and some cloudflare websites(without warp) sometimes have a higher latency and misses(routing to a diff ip for the content) either it could be a cache miss on cloudflares end(this could be possible) or airtel is doing DPI in between. I suspect the later because even popular websites served by cloudflare(which wont have a cdn cache miss) sometimes run oodly slow. My Local isp does not have this problem with the same website on a different computer/laptop/phone(deducing this to a non-cache miss at the cdn level) . Location is Mumbai BTW.
I keep facing inconsistent speeds across different websites myself and I'm using Airtel.
This is such a nice video, so much important information is presented in a easy to understand method in under 15 minutes. also thanks for showing the real problem users face everyday
This happens with me a lot. I think there is some sort of caching happening ISPs end. Because some pages would not work at first but after some time if I retry they would somewhat start working.
Very same thing is true with Flight simulator we are building in Ahmedabad.. Its ISP fault. We have changed multiple routers, modems everything in between!
I guess it's basically the fault of the internet provider because it happens to me sometimes. What happens is that the route the packet is taking becomes lengthy (I don't know the reason, maybe a bad route selection algorithm)
Even RUclips comments is slow in Airtel FTTH, but same is fast in mobile data
Atleast Someone smart pointed this issue out
I use airtel and I too noticed this problem when accessing Udemy. My neighbour using a local ISP gets a flawless access to this site and every others, I'm planning to switch to that soon. Also the customer service provided by airtel or jio is subpar.
This is the reason why i switched to aws instead of using cloudflare rds. I was using jio and spent the whole day debugging code, only to discover that using a vpn solved my problem. Then i switched to aws even though it might be more expensive. No hiccups from there.
9:58 same issue happened to me also. via my jio wifi my website not loading but same via my jio sim (mobile network) working fine
I think the problem is ISP sharing multiple connections on a single public IPv4 (I know that ACT does this and would be similar for small scale ISPs)
and as a result, Cloudflare can throttle requests thinking the public IP as a spammer (since multiple customers have same public IP)
This is so weird that I'm having this exact problem, but with entirely different ISPs and products. I'm trying to connect to a work VPN hosted in another country. Trying to connect to this VPN and using the remote system while on a residential ISP, it'll always route me through a server that has consistently high ping (230-300ms). I have to disconnect and connect multiple times in order to force myself to connect using a faster path. However, the moment I switch to a different ISP, the problem vanishes and I'm able to connect 100% of the time with pings around 100-110ms.
Funnily enough, this residential ISP problem only occurs in the town I live, and whenever I move to a different city and use the same ISP from there, the problem does not occur.
i have same problem with my server, the issue is from ISP, it not able to serve some site or ip for few secs, it generally happens with BSNL, Airtel and GTPL (spl in gujarat). At that time speed test and youtube will be working fine.
cloudflare warp is blocked by many ISP's in India.
This issue has increased significantly in JIO after they implemented the CG-NAT. On top of that, changing DNS doesn’t work with them, it’s not stable. There are high chances that the issue will be resolved when the IP gets refreshed ( In there technical teams words ).
Airtel, Excitel performs really good with minimal DNS change.
The cgnat they mean? It simply lasts till th modem has power un most cases
ISPs dont assign public IP to individual connection. All connections in a building are on Private IP behind a single public IP address. So if there’s any issue with that IP routing than we are simply f’ed. Airtel’s implementation of this CG-NAT is far better than JIO.
India jas gone down the drain. Even the tjings which worked years ago have started crumbling.
Even the drain India is supposed to go down through is blocked. Na Ghar ke Na ghaat ke
At this point I just wanna start an ISP without bs like this but i cant
I am from Gujarat, we are using on premise hosted Application (Web and Mobile). As per the observation mainly the Jio Users are facing this issue. Rest all users can access the application with proper speed.
A lot of things to learn, maybe one day I would work towards understanding all this.
Looking at this without having the opportunity to run traceroute and pinging individual nodes to identify the latency and packet drop, I would say the issue is probably in one of the exit nodes which route the traffic. I'm not an expert in Network Architecture so take it with a grain of salt, I'm hypothesizing that the exit nodes might have some throttling based on route and cloud flare being widely used might be getting throttled or the resources at the exit nodes might be bad. These are owned by TRAI if I'm not wrong or in some cases leased to bigger ISPs by TRAI for maintaining the infra. Usually the work around is to build redundancy but not sure how effective these are. One question I would ask the customer is if they're seeing any increase in performance during non-peak hours like middle of night to rule this hypothesis out.
The issue seems to be because of the contention at peering facilities like Internet Exchange . We were facing same issue and we also have bilateral peering with cloudflare. The problem was fixed after reporting to the Internet exchange. There was also a partial routing issue at some locations which cloudflare had published.
