This is what i came to comments for.

Unfortunately, we have literally dozens of comments that amount to nothing more than schadenfreude, and another handful of non-FANG employees speculating how one of the largest internet operations in existence could improve their game (lol)

I doubt this is the case, but someone on twitter was speculating "what if this is fb's infra team going on strike"

A BGP routing mistake that can cascade into a hard-to-recover-from state of the network where inter-dependencies lock each other.
