We’re gearing up this week to host our first big Internet filtering conference this week, which is already oversubscribed. The event is taking place in Oxford, England, hosted by our partners at the Oxford Internet Institute, in cooperation with our other partners at the University of Toronto’s Citizen Lab and the University of Cambridge’s Advanced Network Research Group at the Cambridge Security Programme. At this event, we will release the full set of data from the first-ever global survey of Internet filtering. In many ways, this release is the culmination of five years of work, since the ONI partners began testing for Internet filtering back in about 2002. The work is thanks to a number of grants, most notably a $3 million grant to ONI from the MacArthur Foundation, as well as key gifts from OSI, IDRC, the Ford Foundation, and others.

Feel free to add a question for discussion to the online question tool.

An even more complete version of this story, including chapters that set the data in context, will appear in our book, Access Denied: The Practice and Policy of Internet Politics, will be released this fall by MIT Press.
