Hi,
the ExoneraTor service (where one can "enter an IP address and date to find out whether that address was used as a Tor relay") has moved to the Tor Metrics website:
https://metrics.torproject.org/exonerator.html
Requests to the previous location are automatically redirected to the new location, which includes all permanent links written/printed on previous lookup results.
The current plan is to leave redirects in place for the next 6 to 12 months, but if there's a good reason to keep them for longer, please let us know.
Just in case you're wondering why we're making this change, it is part of a more long-term effort to bundle all user-facing Tor Metrics content on the Tor Metrics website. Over the past months and years this has affected the Onionoo protocol specification, CollecTor files, the Relay Search service, and now the ExoneraTor service, all of which have been moved over to the Tor Metrics website.
At the same time of changing the location of Exonerator, we're releasing ExoneraTor 3.0.0 which redirects all requests to Tor Metrics. However, redirects can easily be disabled in src/main/resources/web.xml, if requests are supposed to be handled locally.
Please direct any comments or questions to the (public) metrics-team mailing list:

All the best, Karsten
