IT is unknown when their server will be back up. Either check back here, or just try to login.
I'm going to bed now though, but if it comes up, someone else from the site (Probably a member who is trying to login every ten seconds ) will post here and let you know that its back active.
EDIT 5:42AM EST: It looks like its up now. It may go down again/still be slightly buggy. If you get an issue logging in, wait it out for a bit before you start worrying
