"Lessons learned from the Apache.org defacement of 2000" would have been a pretty good title. I still would have clicked, but my expectations would have been differently calibrated. As the title was written, I was expecting Apache.org to be, currently, defaced.
The "from 2000" is not really relevant -- all the same technologies are in use and are likely misconfigured in the same way. There are probably 100s of sites on the Internet that could be owned in the way the article describes.
