Yeah, servercraft hosts their own servers so they're up 99.99% of the time. I know a lot of us are scattered across the globe so it would be pretty impractical to have someone host it all the time. Right now we have 6 - 8 interested in the server, so we can go with the 15 a month, which is a 512 MB of ram server, with a recommended 1 - 8 players. 2 bucks a piece for that (per month mind you) isn't expensive at all. The next step up is the 30 a month server, with 1 GB of ram, recommended 1 - 16 players.
