It's a good thing that admins were at hand and got the servers back online. But may I ask what was the cause of the outage in the first place?
Maybe they are working on adding new 2FA forum patch, but I am just speculation and hoping for this 
I think something strange is also happening with cloudflare, today I got message that I am in some waiting line and that I have to wait for one minute to continue to website... don't know if this is related or not.
