An anonymous reader links to an article at Ars explaining the dropping inventory of bridges
available to users of the Tor project's encrypted messaging system. They're looking for more bridges, but that doesn't necessarily mean buying new hardware per se. From the article:
"After campaigning successfully last year to get more volunteers to run obfuscated Tor bridges to support users in Iran trying to evade state monitoring, the network has lost most of those bridges, according to a message to the Tor relays mailing list by Tor volunteer George Kadiankakis. 'Most of those bridges are down, and fresh ones are needed more than ever,' [Tor volunteer George] Kadiankakis wrote in an e-mail, 'since obfuscated bridges are the only way for people to access Tor in some areas of the world (like China, Iran, and Syria).' For those who want to donate bridges to the Tor network, the easiest route is to use Tor Cloud, an Amazon Web Service Elastic Compute Cloud image created by the Tor Project that allows people to leverage Amazon's free usage tier to deploy a bridge."
