Hi John,
I'm glad I was of help to you

You've been of help to me as well

Yesterday I had the thought that my service provider started blocking their incoming http ports to control the virus. I called @Home to confirm this. I talked to several people until I finally got to their virus control team. He said that they had done nothing that would prevent access to my system and that they were not blocking any ports. These comments had me perplexed given my diagnosis.
My system currently has all of it's existing functionality except that you can not access the web site via http. I was left thinking I had misconfigured something on reboot given what my provider told me.
Based on your response I'm now pretty sure my provider gave me incorrect information ... which means I'd be waisting my time if I tried to fix my server

Hopefully they will restore service to normal in a few days.
BTW, you do not need to change any links on your web site. Your entire site should work fine with https if you are using relative links.
Have a good day and good luck with your provider!
Milan
