Yeah, we get that "too good to be true" quite a bit actually.
If you haven't created an account yet, we have three servers. Johnny is an experimental server. This means he's really only suitable for experimenting. If you're just going to test out some scripts, you're the only person who is going to access your website, and you don't care too much about uptime or speed then Johnny is sufficient. Ricky has less features than Johnny, but has better uptime. The downside to Ricky is, even though he has good uptime, he can be pretty slow sometimes. Tommy is our flagship server. He's got all the features and more of Johnny, even better uptime than Ricky, and he's our fastest server. This is the server we recommend to people when they're done experimenting and ready to run a production website that other people will be visiting.
