That URL:

http://partnerpage.google.com/gtcevent.com

works OK here, using Firefox 2, IE6 and IE7. ISP is Cox cable.

This URL:

http://kthomas.gtcevent.com/

is still failing, according to OpenDNS.

Khris,

You haven't said if the ping results look correct to you.

From what I saw, it is possible that the server at Google is doing what it's supposed to, and the server at Bravenet isn't configured to support the URL it's being sent. Are you sure you have signed up at Bravenet for the service you're expecting?
