Ubuntu Networking :: Cannot Access Facebook Or Netflix From Computers

The problem started happening a few days ago. Only my linux computers are affected. Yup, that's right. My roommates running windows have zero problems.

What's the problem? Suddenly, I cannot access 2 websites: namely facebook and netflix. I just get a "waiting for facebook.com" status from my browser, and it waits there patiently until the browser finally gives up. I haven't found any other sites that give me this issue. Gmail, ....., flickr, etc all work fine.

This happens using both firefox and chrome browsers. I've tried using Ubuntu 10.10 (on my desktop) and Peppermint (distro based on ubuntu, runs on my laptop). Both machines access the internet via wifi. Both have the same problem! o_O

Both machines are up-to-date. I've rebooted many times. I've tried booting an old kernel. I haven't installed any new software lately. I've tried disabling all plugins for the browsers. I've tried power-cycling our internet modem. I've tried changing my DNS settings to use Google's Public DNS service. Nothing helps.

Actually, one small piece of information: If I put my browser in incognito mode, I can get to the "sign-in" page for both facebook and netflix. But upon putting in my credentials, I still cannot reach my custom user home page for either site.
