Hi David,
Thank you, these pointers were very helpful. Do you know if there is some kind of resource that lists known censorship events? I'd like to see how good the approach from the paper does at identifying them.
For Tor-specific censorship, a list that is reasonably complete and up to date is: http://www.eecs.berkeley.edu/~sa499/tor_timeline.pdf. It was composed by mining the Tor issue tracker and blog for events.
For general censorship, I'm not aware of any systematic or complete list of censorship events. There are quite a lot of research papers that study one particular place for a period of time, and from them we know of some incidents.
Here's a list of some measurement papers I'm aware of that might discuss some events. You might also look at OpenNet and Freedom House reports.
