It’s part of Tor’s Join The Network Campaign to get more people using Tor on a more regular basis – and to promote the setting up of relays to help other people use Tor to regain anonymity and access to materials that their state governments might not want them to see…

…including now the ability to run free or nearly-free Tor nodes in the Amazon EC2 Cloud.
