There are people now trying to gain access to the peering routers to implement fixes, but the people with physical access is separate from the people with knowledge of how to actually authenticate to the systems and people who know what to actually do, so there is now a logistical challenge with getting all that knowledge unified. Part of this is also due to lower staffing in data centers due to pandemic measures. permalink source embed save save-RES parent report give award reply hide child comments](https://i.kym-cdn.com/photos/images/newsfeed/002/215/926/0be "an erroneous BGP config change was pushed this morning")
Facebook, Instagram, WhatsApp, and Messenger are down due to a BPG configuration error, not a DDoS attack.
