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 IP version graph

This graph shows the number of relays supporting IPv6 as compared to all relays. A relay can support IPv6 by announcing an IPv6 address and port for the OR protocol, which may then be confirmed as reachable by the directory authorities, and by permitting exiting to IPv6 targets. These sets are not distinct, because relays can have various combinations of announced/confirmed OR ports and exit policies.
