Cannot play, desperate for help

Whatever the fuck just happened, I have no idea what but today I just logged on. Initially I tried typing in nothing at all, no password no username and it didn't have the usual connection problems. When I first say that the message changed I got tfw your heart just swells with hope, dreams and joy. This was rightfully so, I tried the actual login details and for whatever reason I got on! THIS IS FUCKING SICK AS! I'll be joining you guys in quests and whatnot now!
