As I mentioned yesterday on the site news page, the root cause of the community site being down was a mandatory site migration to the webhost's new datacenter (performed by the host). After 12 hours of being down with no solution in sight, I made the decision to relocate the site to RackSpace along with the main site. The hosting costs more, but will hopefully be more bulletproof.
The incompetencies shown by the web host in this site migration are simply beyond my comprehension. These include, along with giving me no notice of the actual cutover and among many other things, the restoring of a 3 week old database (so much for daily backups). And they thought no one would notice?
Fortunately I had a personal backup. Unfortunately, my latest backup was from early evening on Aug 6th. I strongly apologize for the inconvenience of the lost information - please restart/complete the threads that were important to you. Thanks!
