UberHacker uses AT&T just like Luigi700 and they both can't get on. It's a known problem that AT&T blocks the host tolp.net16.net is on... 
Ever thought about using a real, non-free hosting provider?
If things like this become a real problem I can always look into a better host.

Also it's good to know that I make backups of the database every day so we're safe if any kind of shit happens.
I think we need to get back on topic.
