Some GMail servers seem to be experiencing a problem - probably due to someone "fixing" the code on them. (The error, if you get that far, is a Server 500 error. That's usually a syntax error with the code on the server.)
There's nothing you can do about it - just wait it out. It should be fixed by tomorrow. (They shouldn't be playing on a live server, but I'm pretty sure that they took a full backup before they started, so if they can't fix it, they'll just have to restore the backup and try again.)
Google, if anyone there is reading this, PLEASE do your "updating" on a backup server, so the live server doesn't go down.
