As I type this I can't get into Diablo 3. I moved from a state where I was understanding of Blizzard to making the choice to make Diablo 3 a multiplayer game to thinking, maybe they bit off a bit more than they should have with Diablo 3. Perhaps its too much for them to handle because Ive spent more time thinking about outages than playing Diablo 3. Currently at 9.30PDT they are undergoing emergency maintenance:

I hope they clean these issues up pretty soon. That said, when I was in game it was flawless and smooth. Its just the hours of downtime that is a problem. After all this clears up, expect more detailed posts about how fun the actual game is. Oh right, it is fun... When you can play it.

PS Error 37 & 3003, I hate you.

Update from blizz:

"We're continuing to work on the issues currently affecting the Americas region, which are resulting in failed login attempts and service issues. While we've identified the causes and are working to resolve them, we expect our efforts to require an approximate two hours to complete. We expect game services to fully return by approximately 11:45 p.m. PDT. We apologize for the downtime, and appreciate your continued patience."

So frustrating.
