Version 134 (modified by ln5, 2 years ago) (diff)


The Tor Project runs quite a lot of services for developers, researchers, relay operators, and the community at large. Each of these services, regardless if developed by The Tor Project or by a third party, should have one or better more maintainers who look after the service if it breaks. In particular, fixing a service is not something our system administrators can or should do. As a consequence, unmaintained services will be shut down.

  • New service will only be started if someone agrees to maintain it for at least the first six months.
  • Existing services that have a maintainer and become unmaintained will be shut down three months after discovering that they are unmaintained, unless a new maintainer shows up.

The following table lists services run on torproject infrastructure. Follow the link the service name column for additional information.

Corresponding onion services are listed on
