A traceroute simply shows the 'path' on the Internet between the host where the traceroute is run and the destination that's specified as well as where, if anywhere, the route is failing to complete. In the single-firewall scenario, a firewall is placed between the external network and the web server. Plusnet may be blocking port 80, but if they where then I'd have thought port 443 would be blocked as well. Lastly, keeping port 80 open in order to serve a redirect helps get people to the right version of your site (the HTTPS version).
