Heya,
The site is going to change servers tomorrow (Friday) 2/15/2013. I found a great deal for a VPS that costs less, has high reliability, and has more resources than what we're getting now.
You probably won't even notice the switch. If you do come across a "this site is down" message on the old servers, it just means your DNS servers (the servers that point the IP address to the domain) hasn't updated yet. They usually update pretty quick, within a few hours, so just check back later.
