Servers seem to be coming up a little earlier than the most recent estimates, though there aren't a whole lot of them up yet. As I write this, there are only a dozen or so servers active and ready to go with more coming up every moment. Update: Looks like most servers are now up at this point, if not all of them. Huzzah!
For those of you who are on vacation and are eager to play, go on! Have fun! Hopefully there will be no more issues today and your holidays in Azeroth will be uninterrupted. For those of you who are sitting at work or school right now, I am sorry. Come over to my place, I'll share my cookies with you.
And no, I don't play on Argent Dawn. Sorry! Lowbie alts for the win.
