Tor's site was blocked in Turkey in March 2014: http://cartography.io/

For the event described as "Iran – 2013 – TCP reset on all non-HTTP": this was actually a traffic shaping behavior that matched TCP connections against a whitelist (HTTP or HTTPS), if the connection did not match this behavior, then the throughput was throttled down to 1 packet per second after sixty seconds. Psiphon's bypass mechanism was to prepend "GET / HTTP1.0" in front of traffic streams.

Hi all, 

I am trying to make a list of events when different censorship regimes blocked Tor.

The goal is to understand the censorship arms race, especially capabilities of current censors and how long it took Tor to resolve those issues. 

The attached pdf has all the events I could find. 

I collected these events from the Tor blog, the bug tracker and the censorship wiki.

For some of the events I couldn't find any dates and also I'm not sure if this is a complete list of all the censorship events. 

Can any of you help me find dates of some of the events or direct me to other sources of information to find more events?

Thanks!
