I just tried to log in with Mozilla and Chrome. I have tried making new characters. I can't get into the game at all. I have updated Java and Adobe. I don't know what else there is for me to do.

EDIT: I have tried other computers and browsers. Safari, IE, Mozilla and Chrome none work. I am going to safely assume the server is down.

Server works, but there was a game-breaking bug. It has been hotfixed. Unfortunately I cannot fix these things from work. I read your post and felt immediate dread when I realized what I broke.
