> 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
>> 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?
