Both google and RHN use floating (location aware) IPs so there is never a guarantee you're hitting the same IP each time. If you have a firewall rule that is explicitly allowing access to certain IPs then it could be the cause of your problem. With Google we ended up having to open various ranges of IPs to access news.google.com and with RHN there is a change you can make to specify static IPs for firewalled servers.

So the question is: Do you have a firewall (or firewall rules at host level) that are only allowing output connections to explicit IPs?

Is it only google.com or do you mean all sites?

Be sure to use www.google.com too.
