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

> The goal is to understand the censorship arms race, especially

> 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?
