DNS Issue

I recently solved a problem with my ISP's DNS lookup. Google Chrome was waiting forever on loading pages that weren't already DNS cached. I could tell this because they spent a long time on the "Resolving Host" phase, then they would report back with "Page Unavailable".

While the responses didn't usually take more than a few seconds, there was definitely a problem somewhere. I then changed my DNS in windows to use the Google Public DNS.
