Any time one of the Alexa top 10 sites has an outage, you can expect to see a ripple effect of errors reported to DownDetector across other unrelated sites. [image: 20210518.png] For example: - when users can't get to any major service, they often blame their ISP, accounting for the spikes to Spectrum, Comcast, Cox, AT&T, Verizon, T-Mobile, CenturyLink, Frontier - those eyeballs have to go somewhere, so they're going to visit other services, leading to a surge of traffic to them. A fixed percentage error rate will lead to a surge in errors corresponding to the surge in usage. This may account for the spikes to Reddit, Netflix, Xbox Live, Discord, Roku, Twitter, Facebook, Cloudflare, and Snapchat Figuring out whether you're looking at a ripple effect, or a nation-state attack on a core router, is left as an exercise for the reader. In this case, it was just a YouTube issue: https://twitter.com/TeamYouTube/status/1394862840960327680 Damian On Tue, May 18, 2021 at 9:43 PM Jay R. Ashworth via Outages < outages@outages.org> wrote:

Given the current world events, wouldn't be surprised if a Nation State was trying to do some censorship and fat fingered their peering links.
Not impossible, and part of the reason I posted it. Multiple focal centers generally denote an attack -- though the topology of the Internet can make it difficult to discern whether there were in fact multiple focal centers -- no doubt Renesys, and some of our regulars here, will have more data.
Which we'll put on -discussion. :-)
