I think it's at the point now where you either go to bed or play something else:
From Rockjaw:
'Hey everyone, so as you know we've been offline for about two hours right now.
What initially seemed like a "Weird, let's restart" problem is now something more perplexing. All of the available engineers are looking at this. It's doubly weird because as you may know, we have this build in Test Center right now, where it seems to be working just fine. (In fact, you can go ahead and login there if you wish.)
Unfortunately as we're still in the 'investigation' stage, we can't tell you with any certainty when the servers may be back online. At minimum, it will be several hours from now (8:11PM PDT). There may have to be an additional server work done, possibly a server build may need to be pushed out. It's hard to say.
When I'm given more information I'll pass it along. For now, please sit tight, download the patch, and take a look at the patch notes. Thank you.'
