The Tor browser is used by many to stay anonymous online - and it's something that has been embraced by the likes of WikiLeaks (opens in new tab) as a way to safely gather information whilst hopefully avoiding the surveillance of the NSA (opens in new tab)
One lesser known project from the same stables is the Tor Cloud (opens in new tab) service, and Tor has announced that it is closing down.
Based on the Amazon EC2 cloud computing platform, Tor Cloud provided a way to share computing resources and allow faster uncensored access to the internet. However, the project is plagued with "at least one major bug ... that makes it completely dysfunctional" and after failing to find anyone to undertake the work, the decision was taken to shut Tor Cloud.
This does not mean that Tor itself is dead - far from it - and developers are being encouraged to create their own forked versions of Tor Cloud.
It is still possible to manually install Tor bridges on Amazon EC2 and other cloud platforms, but it is now not as simple as it was with Tor Cloud. Any existing instance of Tor Cloud remain unaffected by the closure of the service as all of the necessary settings are already in place. There is still the problem of numerous known bugs (opens in new tab), but this is something that users and developers are free to work on.
