Aaron,
Go Start >> All Programs >> Accessories >> Command Prompt
In the Window type:
Ping 64.235.225.26
And then hit Enter.
When it completes it will show you the results of trying to ping the IP Address just like a sub using Sonar. If it times out we know it cannot see the site at all and that is a different problem vs trying to get DNS Resolution.
Then try it with:
Ping 64.4.241.33
Let me know if the pings get though or not and how long they take.
Take Care,
Richard
