This was happening to me. (Score 1)

I have been getting connections reset on and off the the past week or so on Comcast. I found that if I did an nslookup, it was only the first IP address that had problems. The others worked fine, so I just browsed to http://72.14.207.99/. Unfortunately, trying to use the iGoogle home page redirected back to http://google.com/ig and was reset, but the web search worked. You could probably modify your hosts file to get around the resets if one of their IP addresses works.
