Starting at approximately 18:00 EST on December 14, 2004, Sears began blocking all incoming requests from my public IP address, most likely due to the GrabPERF testing I do from here.
How do I know it’s a filter and not a performance issue? Well, when I re-route traffic through one of the many thousands of open proxy servers available, the page comes up instantly. Also, they are doing a smart thing, and not sending an explicit TCP Reset; they are simply routing the TCP SYN requests into the "bit bucket" — a DROP rule for firewall wonks out there.
I have terminated testing of this site. Guess this means my wife can’t access her order information for the oven part — my bad.
