Every now and again google.com doesn't load. I can get to google when I ping it, and then I just use the server and I can get to it(like http://eh-in-f99.google.com )
Then randomly it will work again. My roommate who is connected with our router, has the same problems with it also.

gmail.com works, yet not images.google, or google.

Resetting my router(DHCP release and renew) doesn't fix it.

Any suggestions? I tried searching google, but it doesn't help.
