Obfsproxy Bridges in the Amazon Cloud
The Tor Cloud images for all the seven regions have been updated to fix a bug found in the unattended-upgrades configuration. The normal bridge images have also been updated to include obfsproxy, which attempts to help users circumvent censorship by transforming the Tor traffic between the client and the bridge.
If you are already running a Tor Cloud bridge, you will need to either manually update your image, or set up a new Tor Cloud bridge and terminate the old one. If you decide not to take action, your image will fail to upgrade Tor correctly and will not be running as a bridge.
If you just want to fix the bug in the unattended-upgrades configuration, do the following; log on with SSH and edit /etc/apt/apt.conf.d/50unattended-upgrades to say precise instead of lucid.
So when I terminate the tor cloud bridge and go to set up a new one the old one is still there. The option is to launch it or a new one. This being the second up date since I started the tor cloud there are now 3.
So do you just start a new one and end up with who knows how many or can the old ones actually be deleted. And please answer for the layman.
