How relay listings are grouped

Groups reflect recent activity and verification, not popularity. Within each group, open relays are shown first, then restricted, closed, and unreported relays.

The ActivityPub Actor identifies a relay and describes its capabilities. The ActivityPub Inbox is where it receives ActivityPub messages. Learn about the ARD White Pages Protocol.

ARD White Pages Protocol Relays
These relays self-report through the ARD White Pages Protocol and have recently passed an ActivityPub Actor check.
Other Known Relays
These relays have one recent sign of activity: a heartbeat through the ARD White Pages Protocol or a successful ActivityPub Actor check. Some report through White Pages but have not passed both checks.
Offline or Unreachable Relays
These relays have no recent healthy heartbeat or successful ActivityPub Actor check. They may be offline or temporarily unreachable, but were last confirmed online within the past 30 days.
Graveyard
These relays have not been confirmed online for at least 30 days. They remain listed for reference and are checked periodically in case they return.
