I don't want to steal Gina's thunder, but this is the latest update on P411 she shared with us on another board.
P411 Update:
We are dealing with a Denial of Service attack out of Asia.
http://en.wikipedia.org/wiki/Denial-of-service_attack
The short version (how I understood it) is that we are being hit over and over, by thousands of malware infected computers, which is overloading our servers and bringing the site down. We have people working to block the attacking ips, during which time the site needs to be completely offline. Once all of the ips have been blocked, we'll put the site back up.
Thank you for your patience, it's been a rough day for everyone.
Always,
Gina
