nicht nur DNS auch das Routing wurde weggefickt - RIP
The root cause of the worldwide outage appears to be a flubbed BGP route update.

Not long after that, Reddit user u/ramenporn
reported on the r/sysadmin subreddit that BGP peering with Facebook is down, probably due to a configuration change that was pushed shortly before the outages began.
According to u/ramenporn—who
claims to be a Facebook employee and part of the recovery efforts—this is most likely a case of Facebook network engineers
pushing a config change that inadvertently locked them out, meaning that the fix must come from data center technicians with local, physical access to the routers in question. The withdrawn routes do not appear to be the result of nor related to any malicious attack on Facebook's infrastructure.
