No, I'm still hammering my login info every now and then. I'm surprised actually, because Blizzard is usually puntual when it comes to bringing servers back up... Ten or fifteen minutes late, okay, but they're pushing an hour now and the unlisted servers are not back up yet... And their site doesn't work either, I think it's volume.
I agree, WoW became too big for its own good. I'm not sure they originally expected such volume though.
