Thanks everyone.
The website was moved to a brand new Dual Opteron setup (Dual AMD Opteron 265 x2 (dual core) processors), 4GB RAM, 3 SCSI Disks and 1 SATA Backup drive yesterday running Gentoo Linux. I'm still in the process of fully setting up the server - if you could let me know the time w/ timezone that the website is down in future, I can look into what's causing it. I haven't received any notices of failed/restarted services from SIM.
I'll be posting an announcement shortly... they're tricky things to write, ya know.
Cheers,
Scott
