There was the finals of The FIDE Chess Olympiad going on between India and Russia when this outage started. 2 Indian players lost connect to Chess.com at this time and ended up losing their games on time. This ensued a lot of drama. In the FIDE ended up declaring both India and Russia as joint gold medalist. Russian players were not happy. Also Armenia had forfeited from tournament as they had faced similar disconnection issue against India during quarterfinals.<p>Here are a few links if you want to follow the drama:<p>BBC: Chess Olympiad: India and Russia both get gold after controversial final [1]<p>YouTube: Joint Gold for Team India and Russia at the Online Olympiad 2020 | Full [2] story<p>FINALE!!

Google networking SRE here (my team runs ns[1-4].google.com among other services).<p>Regardless of original intent, the blog doesn&#x27;t land well with me. It could have provided the background on flowspec, using their own past outage as a case study, without any of the speculation or blameyness that came across here. The #hugops at the end reads quite disingenuously.<p>We see other networks break all the time and we often have pretty good guesses as to why. But I personally would never sign off on a public blog speculating on a WAG of why someone <i>else&#x27;s</i> network went down. That&#x27;s uncouth.

sometimes people remark at how extensive ancient civilations became with such simple technology, yet here we are. billions of people being served by things like BGP and SS7.<p>as i get older, i become more and more concerned with humanity&#x27;s lack of fault tolerance.<p>brett weinstein clued me into this as an evolutionary phenomena. if a gene activates a short-term solution and long-term problem, that gene is likely to be favored.<p>how do we transcend this problem that seems to be inherent with existing? a first-principal problem?

I love Cloudflare’s writeups and Cloudflare in general, and while this was again well written and excellent analysis, it contained a tad bit too much speculation for my taste.

Horror thought: if the internet ever &quot;breaks&quot; enough that all access to StackOverflow is lost, no one will be able to fix anything to get it back up, and we&#x27;ll be back to the stone ages to start again.<p>Kidding. Mostly.

Did other providers have similar issues to Cloudflare? I only noticed cloudflare sites being particularly down, not other CDNs, but maybe that was selection bias?

I wish we could read an analysis from CenturyLink. Their status page doesn&#x27;t have anything useful: <a href="https:&#x2F;&#x2F;status.ctl.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;status.ctl.io&#x2F;</a>

BGP and its associated tools is beginning to look like a national, actually global, systemic risk.

Bit off topic. Does anyone know the reason why Centurylink doesn&#x27;t operate in California?
