[outages] The Internet is down.

[Damian Menscher]

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.

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:
