Yesterday, I got a new server with CleverKite named Galaxy. MLP Forums, being the largest site I host, is already up and running on it. Today, I'll be moving Wii U Go and TheWiiU.com over to it as well. Expect some serious speed improvement once the move is complete.
Downtime will hopefully be under an hour, as I've set the TTL's on both sites' domains to 5 minutes, but don't be alarmed if the sites remain inaccessible for 48 hours.
