A while back, I posted about my problems with US West. Basically this kind of stuff was happening to me a LOT. It hasn't happened much since then, but I think it's because I switched my time of play a bit.

every now and then I still get realm down. Something that's come up a lot more is not being able to join or create games. I'd go in with my sorc to mf or do baal runs and I can't join or create. It just sits at the screen with that picture of a door that doesn't open, then after about half a minute to a minute, it'll give a message saying Unable to join game. When I switch to my other chars (same account), it's fine. I wait 5-10 mins then go back to my sorc and everything's dandy again.
