Type "cache:http://dtuite.github.com/define-custom-vim-tags-and-labels.h... into Chrome's address bar and hit enter to see the content.

The repo is no longer visible (http://davidtuite.com/define-custom-vim-tags-and-labels.html), so I'm guessing it was either deleted or made private. The CNAME file in that repo probably inadvertently pointed to "onlyvariance.comdavidtuite.com" and GitHub is still caching it.
