The opening announcement on the login screen has just let us know that there is urgent maintenance being performed on the authentication servers. The maintenance will continue until 1:00 p.m. PDT / 4:00 p.m. EDT.
During this time you may or may not be able to log into the game. Pretty much the luck of the draw and beyond your control.
Account management and posting on the forums will be offline during this time as well, so the troll's trolling will have to terrifically terminate 'till temporally soon.
We'll update this post when things are back to normal, or if there are additional issues.
