The CF post mortem looks sensible, and a good summary of what we all saw from the outside with BGP routes being withdrawn. Given the fragility of BGP, this could still end up being a malicious attack. -mel via cell

I believe that the above link refers to a previous outage. The duration of the outage doesn't match today's, the technical explanation doesn't align very well, and many of the comments reference earlier dates.
Also, Cloudflare’s take on the outage - https://blog.cloudflare.com/october-2021-facebook-outage/ <https://blog.cloudflare.com/october-2021-facebook-outage/>
This appears to indeed reference today's event.
