WP Site: www and wiki not loading.

I mentioned this in #wordpress:
When attempting to view https://www.www.ads-software.com or wiki.www.ads-software.com, the site refuses to load. Firefox 0.9.1 (Mac) reports that the address could not be resolved. However, visiting www.ads-software.com (no www) works fine (this is how I’m posting to the site now).
Thought you’d want to know, in case anyone else is having this problem.
