Servers

Country and ISP diversity are approximated by resolving IP addresses to a country code and an autonomous system. We process the capabilities and properties relays and bridges reported to directory authorities.

  • Relays and bridges
  • Relays by relay flag
  • Relays by tor version
  • Relays by platform
  • Relays by IP version
  • Bridges by IP version
  • Total consensus weights across bandwidth authorities
  • Monthly uptime of relays
  • Network churn rate by relay flag
  • Network bubble graphs
Relays by tor version graph

This graph shows the number of running relays by tor software version. Relays report their tor software version when they announce themselves in the network. New major versions are added to the graph as soon as they are first recommended by the directory authorities. More details on when these versions were declared stable or unstable can be found on the download page and in the changes file.
