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
  • BridgeDB requests by requested transport
  • BridgeDB requests by distributor
  • Top-10 countries by relay users
  • Top-10 countries by possible censorship events
  • Top-10 countries by bridge users
  • “The anonymous Internet”
Bridge users by transport graph

This graph shows the estimated number of clients connecting via bridges. These numbers are derived from directory requests counted on bridges. Bridges distinguish connecting clients by transport protocol, which may include pluggable transports, so that graphs are available for different transports. For further details check the documentation on Reproducible Metrics.
