Their problem was that they only have two transit providers, and one of them black-holed about 3-5% of the internet. Since it was a routing issue, I'd guess it was either a misconfiguration, or that the traffic is being split across dozens of paths, and one path had a correlated failure.

      Sure, maybe the underground tube was breached while someone was moving goalposts?
