We have upgraded to a new faster server.  Our old server was running on a single P4 with 1GB of ram, and now we are running on:

• OS: Linux Ubuntu
• CPU: Intel Core 2 Duo - 2.13 GHz
• RAM: 2 GB
• Storage: 2 x 300 GB hard drives
• Bandwidth: 1,000 GB per month

The new server costs $100/month so don't forget to visit the store to help keep upgrades like this coming!
