404 message
I've had it happen twice, too. I'm friends with a few fellow rpol-ers on social media sites, and they were locked out at the same time. The main page was still visible and accessible (probably why rpol didn't come up as being down for donsr's verification site), but every forum and game gave the 404 error. The first time it was only an issue for about 15 minutes or so. This time, it was about an hour.
