@@mr.cauliflower3536 Allegro is a marketplace, where individual sellers list their offers. Warehouse workers in Poland don't have it that bad. Many employers who never thought of themselves as pickers or packers actually love working for Polish e-commerce businesses, because it's lightweight job. I have never heard of cases of exploitation attributed to amazon warehouses. There are also lots of logistics and fullfilment centers, as well as Allegro owns their official store and offers Allegro fulfillment to sellers recently, but as far as I know most logistics employees are fully satisfied with their job, many e-commerce owners also becoming delivery couriers and similar cases.
I don't know Allegro or whether they have had any controversies but not only did they fix the issue within 25 minutes, they even gave vouchers for the very phone to people who couldn't make the purchase. Pretty darn good if you ask me.
Yeah Allegro has pretty good customer support, handles shipping and returns extremely well, overall the experience is very good. I almost always use Allegro for online shopping, just because they make the shipping and returns easy.

Good Video! I hope you will make one about the recent Cloudflare outage where PDX-04 failed. As usual, they mad a post mortem that is pretty fun to read
i actually never expected a video about Allegro of all things, let alone such a wild occurence i never knew about despite our family's frequent use of it, quite a pleasant suprise though
I love the Aqua Teen Hunger Force-style explosions whenever things go wrong (for those that don't know, most of the time if a character threw something on the ground it would explode for no particular reason)
I love this channel. It’s like fireship but for security and infrastructure and that’s a good thing. You guys should collaborate and truly break the internet (by causing the monthly cloud flare outage)
@@phusicus_404 because Allegro is combination of Amazon and eBay, especially that second. Allegro from the beginning was auction website like eBay, shops was added later. Amazon and eBay also tried to introduce itself here in Poland, but strength and influence of Allegro is too high. In Poland we buy mostly on Allegro or Aliexpress.
Although my only connection to aviation is as a passenger, I still enjoy his videos. It's the same with Kevin Fang's videos except it's a lot more relevant to me.
just gotta say the allegro zone on the Woodstock/ Pol and Rock festival is pretty good was 3 times there already (very nice festival btw and its FREEEEEE )
Talking about Poland… I remember some time ago our government launched an app that works like an ID on steroids (very handy btw). Some PR smarty pants decided it would be a great idea to announce a simultaneous launch in entire country at once. (Spoiler: it was not xD)
We have the same thing in Ukraine, called "Дія"("Action" in English). It also allows to keep other documents there, not just ID. It allows to use more then 100 different services such as receiving certificate of income, monetary assistance at the birth of a child, etc. And there are sometimes polls such as "Leave September 8th as a holiday?". I am surprised how few countries have such a program.
Absolutely; the largest telecommunications outage in Australian history. 10 million customers* across mobile, landline POTS and NBN could not get even basic service for 8 hours. Optus landlines couldn't even ring the emergency phone number 000. The post-mortem on that will be very interesting indeed. *10 million customers affected, and Australia's population is 27 million. More than a third of the country.
@@3rdalbumid hope that theyll publish technical details about what went wrong. I feel like this time they might given the pressure from the Australia government
way too much of my backend/infra knowledge is coming from these videos, they are just so close enough to reality that my silly brain can understand them as realworld examples :)
Did not read about this event back then, but very informative. Everybody can learn lots of stuff from your videos. Not sure, if it really fits in your scope, but do you plan a video about M$s master key incident?
i would love to have modern hole punch cards would be so cool. Id buy a modern hole punch machine ad the necessary paper. Absolutely loved the video so funny but also good explanations.
Great video! Similar instances of these scaling problems are ticket master and concerts too. Since their web server instances failed on a couple of times, when fans bought tickets. For various artists. Also, I took my Amazon CCP! So I think I understand what's happening in this video hahahaha.
Not changing the default open file limit is a pretty nooby mistake. I'm amazed they didn't notice it before as it doesn't take much to hit 1024. Also when it does, it's very clearly logged.
Love your videos man, don't know if you ever gonna see this comment, but wanted to leave a shout out as your videos taught me a lot and encourage me to pursue a career in Cybersecurity and I finally manage to land a job as an Identity and Access Management Developer.
