Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi, I just want to make sure I have everything set up correctly for the launch, I know the servers aren't up yet.

When I login atm, I get a login success but then it is followed by Disconnected from Server, is this what other people are getting? I see others have tried to login and they get told that their details are wrong, so just wondering why I get this different message.
