I have set up a web server on port 80 and tested that it works locally. Several weeks ago I signed up for a dyndns hostname (the free service) and about a week ago I used the dyndns hostname to access the site and it was working (it was also successfully accessed by several other people).
However, today I tried it again and it simply doesn't load the page (literally I see a blank page, it says "loading" for a while and then "done" but it's still a blank page). I tried telneting to the hostname (as well as straight to the IP) on port 80 and it disconnects after it times out i.e. it doesn't load anything.
I have checked the following: - my server is up and running on port 80, - my IP address is indeed the one shown in the dyndns service page, - I have not made any changes to any firewalls/routers since last week (when it was working), - the dyndns service has not expired.
Does anyone have any suggestions for what could be going wrong? Thanks.

Have you tried forwarding a different port, just in case your ISP has started blocking port 80/TCP?
