Also, if it takes you until after maintenance for the system to force log you off, you should be able to then contact support and ask your sub time be extended to make up for this downtown. They may not have the ability to manually log you out, but should be able to credit your account for the down time when you do get back up and running again.

Actually, if you don't mind... Where were you before you tried to teleport and where were you trying to port to? I might be able to login and check this myself.
