Breaking up scheduled programming to post this slightly unscientific post:
Based on the people I have grouped up with in the past hour or so; if you pre-purchased Cata, unlocked it, and downloaded that patch fully, you will start to randomly disconnect within three minutes (tops) of loading up the game. And then you will keep disconnecting. This started fairly recently, and I can only base this one the info I gots at hand yall, so don’t beetch if I am not 100% on this.
If you have pre-purchased the game and have not yet tied it to your account/downloaded the Cata patch that comes with doing so, I would wait a few more days to do it. You will still need to download it to play once Cata ships, but if they do not fix this shortly, you will not even be able to play WoW at all until they *do* fix it.
Just a heads up. It’ll probably be fixed by morning.
