ETA on Servers ?

I'm sorry Blizzard, I know you're not allowed to answer this, normally, but it affects an entire battlegroup and as far as I know, it's been down for the last 2 hours..this indicates that at least something "broke".

Can I go and grab a few movies for this evening, or can you say with reasonable certainty that the servers will be back "soon", hopefully meaning this evening :P

Edit: I know you're probably working your asses off and I personally have to say, that these last 6 months have been the most stable I've experienced, so you have my gratitude already ;)
