Same thing here,got a few error messages while trying to hit this site but starting saturday I had problems getting on to any php hosted site. I put it down to "Santy" untill I noticed others having problems logging in or getting timed out.
I think Zone alarm had something to do with it. I had to allow third party cookies and private headers to get on any php site or would get weird error messages.
I didnt change any settings and all security scans showed my box was clean.I can replicate this error by unchecking those two options in zone every time.
Could Santy be causing Ddos attacks on all php sites?

Partially Santy and it's variants plus we quite often get DDoSed anyway being a 'security' site.
Our host is using an anti-DoS device now in front of the box, the problems people were having was due to this device dealing with the attack, it was dropping some of your SYN packets as attack packets when you tried to connect to the site along with those from the 'real' attack. So the site was up, just that at times it was hard to establish the full 3-way handshake.
There are some good papers here about DDoS mitigation strategies:
