anyone having problems with the master server?

it is usually very reliable except for the last 24 hours or so my demo is not showing up after registering with it such that my testers can connect to my game because requests get timed out. When I look at the Gnome Tech Master Server Monitor it shows my demo presumably under game server type "Test App" but the details screen times out. Same with type "FPS Starter Kit" but other types seem to work. Could this be a problem on the master server side? thanks
