Here is a good technical article on what transpired today, it doesn't explain why.. that will come out in a few days maybe.. but it is a good overview. They were completely gone, no record of any of their stuff existed. For us it was a busy day, we received a record number of calls, and a lot of people reset their modems to factory defaults etc.. so we've been busy and are still catching up...
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.
