Comcast Blocks port 80

If you host your own webserver and Comcast is your ISP you can kiss serving webpages good bye. At least for now. Since today it seems Comcast has blocked incoming requests port 80. Port 80 is the main port where most of your web traffic goes through. I’m not sure why. Maybe it’s to prevent people running business websites off a home-based ISP account.

I have switched my web server to serve pages through port 81 and have my Dynamic DNS auto-point to this port for all HTTP requests. I hope this is just temporary. I’m sure Comcast’s customer service will be flooded with calls tomorrow morning.
