I apologize for any "inconvenience" the problems to the site have caused. It seems like they figured out what the problem was.

From the support guy at my hosting service...

"Someone was actively poisoning the server. I've got them locked out via our firewall. They would start HTTPD connections, then not complete anything. Denial of service attack.

They had 30 Apache processes tied up before I put a stop to it."

Who knows if it was my site they were after. I always wanted one of these threads...
