Honestly, based on the fact that the page starts to load before giving a DNS error, my guess would be that the page includes content from another domain - this could be images or media from another site, or even ads from an adserver - where the remote server is no longer available. I would guess that you are using IE, since I don't think Firefox errors out the entire page when a problem like this is encountered. Try using Firefox and see if the problem goes away. Note that you may see areas of the page that are blanked out or which contain error messages. You can use this information to contact the site administrators about the problem.
The only way to learn anything is to question everything.
