Just popping in to say I have this problem as well, currently. Couldn't get on at all last night, and I tried again today; it let me choose my character and all that, but when it got to the loading screen, it sent me back to the login page. And now it can't find the server... I haven't checked my internet connection but it seems to be working fine on the other computers in my house.
So uh, yeah, just saying you're not alone PlanetSpunk. xD
