[outages] Facebook Down

Tue Oct 5 01:40:05 EDT 2021

First I love this list, but come on y'all. I've gotten like 50 or 60 notifications about this today. Please take it over to the discussions thread.

For the rest of the unsubstantiated. As of 2100UTC Facebook has started resuming communications.

Here are some major relevant posts for everything known so far.

Understanding How Facebook Disappeared from the Internet<https://blog.cloudflare.com/october-2021-facebook-outage/>
Today at 1651 UTC, we opened an internal incident entitled "Facebook DNS lookup returning SERVFAIL" because we were worried that something was wrong with our DNS resolver 1.1.1.1. But as we were about to post on our public status page we realized something else more serious was going on.

It's worth noting that all these emails to the list are arriving on my
(independent) mail server late and out of order.  Unlikely to be
coincidence.

Somebody on Twitter said that the CEO of Cloudflare said that all of
Facebook's BGP routes "had been withdrawn", but that Tweet wasn't
from any particularly reliable source.  Still the problem does seem
go further than just DNS for Facebook properties.
