Query: Dimming the Internet: Detecting Throttling as a Mechanism of Censorship
  in Iran   In the days immediately following the contested June 2009 Presidential
election, Iranians attempting to reach news content and social media platforms
were subject to unprecedented levels of the degradation, blocking and jamming
of communications channels. Rather than shut down networks, which would draw
attention and controversy, the government was rumored to have slowed connection
speeds to rates that would render the Internet nearly unusable, especially for
the consumption and distribution of multimedia content. Since, political
upheavals elsewhere have been associated with headlines such as "High usage
slows down Internet in Bahrain" and "Syrian Internet slows during Friday
protests once again," with further rumors linking poor connectivity with
political instability in Myanmar and Tibet. For governments threatened by
public expression, the throttling of Internet connectivity appears to be an
increasingly preferred and less detectable method of stifling the free flow of
information. In order to assess this perceived trend and begin to create
systems of accountability and transparency on such practices, we attempt to
outline an initial strategy for utilizing a ubiquitious set of network
measurements as a monitoring service, then apply such methodology to shed light
on the recent history of censorship in Iran.
