The Beta launch has been delayed twice today..
It was supposed to start 1500GMT today, but it's delayed until 2200GMT now and that's midnight here in Norway and I'm going to work tomorrow and wont be home again until Saturday..

But it's probably best to wait a couple of days until they've sorted out the worst bugs.
I doubt that it will be very stable today or tomorrow..
