My www. subdomain won't load a page.  It gets either 1 or 2 connections and then the browser times out and shows a blank page.  The other subdomains work (ftp. irc.)  I closed my browser, cleared my cache, and flushed the dns, but HFS still shows just a status of "Requesting" and nothing more.  All three HFS instances running are affected.  I closed HFS and reopened and loaded the default template.  I checked my DNS provider for the proper IP.
Everything seems fine.  How did I break it and how do I fix it?
