Users

We estimate the number of users by analyzing the requests induced by clients to relays and bridges.

  • Relay users
  • Bridge users by country
  • Bridge users by transport
  • Bridge users by country and transport
  • Bridge users by IP version
  • Top-10 countries by relay users
  • Top-10 countries by possible censorship events
  • Top-10 countries by bridge users
  • “The anonymous Internet”
