Just tried logging in and connected to the login server with no issues.
I'd suggest restarting either your router/residential gateway and/or your computer.
This has happened to me before and it's usually when something is going on with the servers. My internet never went down, no other internet based programs had any issues. The ONLY program that had issues was rom. This isn't a flame against you, but I love when something like this happens and the default answer involves restarting my system. Might want to ask a few more questions to even determine if my system might be involved.
