The Tor project, whose network tool helps people avoid online censorship, works by bouncing traffic around several different computers before it reaches its destination. The more computers there are in the Tor network, the better it works. Now, Tor’s developers want its supporters to set up Tor “bridges” on Amazon’s cloud computing platform, EC2. EC2 has a free introductory offer and there’s an easy Tor image that is configured and ready to go — but if you don’t qualify for the free offer, you can donate a powerful Tor bridge for as little as $30 a month, and help people all over the world who want to be more anonymous and more private.
Setting up a Tor bridge on Amazon EC2 is simple and will only take you a couple of minutes. The images have been configured with automatic package updates and port forwarding, so you do not have to worry about Tor not working or the server not getting security updates.
You should not have to do anything once the instance is up and running. Tor will start up as a bridge, confirm that it is reachable from the outside, and then tell the bridge authority that it exists. After that, the address for your bridge will be given out to users.
