 reachability input list]). Having such a format ensures that we are going
 to have the input list up to date. Ideally this should also happen to the
 bridges (at least the ones listed in Tor Browser), directory authorities
 are not changing that often.

 No, we don't provide custom fallback formats for each downstream consumer.
 Instead, we have a spec that can be used to parse the list:
 https://gitweb.torproject.org/torspec.git/tree/dir-list-spec.txt

 The fallback file is currently used by Stem and Metrics (Relay Search).
 OONI can use it as well.
 It should be very easy to parse the IPv4 address, DirPort (HTTP/TCP), and
 ORPort (TLS/TCP), and the IPv6 address and ORPort (TLS/TCP).

 I recommend you use the fingerprint as the "nickname", because fallback
 nicknames are not guaranteed to be unique.

 In future, we will make the authorities file into a separate list
 (#24854), and change the format so it's easy to parse (#24818). We also
 want to change the fallback format so it matches the authority format
 (#24852).

 > The relevant OONI ticket: https://github.com/OpenObservatory/ooni-
 resources/issues/11

 I don't think there is anything that core tor needs to do to make this
 happen, so I'm closing the ticket.
 (Tor Browser's default bridges are maintained by the Tor Browser team. You
 should probably parse Tor Browser's bridges file as well.)

 Thanks for the terminology note, updated the ticket accordingly.

 Perhaps the contents of `fallback_dirs.inc` should be populated in a
 format (ticket:25534#comment:2) that can be added directly to ooni-
 resources repository ([https://github.com/OpenObservatory/ooni-
 resources/blob/master/bridge_reachability/tor-bridges-ip-port.csv|bridge
 reachability input list]). Having such a format ensures that we are going
 to have the input list up to date. Ideally this should also happen to the
 bridges (at least the ones listed in Tor Browser), directory authorities
 are not changing that often.

New description:

 The OONI probe TCP connect test (run by default from many probes)
 currently tests the TCP connectivity (successful connection: true/false)
 of the directory authorities and brigdes.

 This ticket is about adding the fallback directories
 (https://gitweb.torproject.org/tor.git/plain/src/or/fallback_dirs.inc)
 to the TCP connect OONI probe test (https://github.com/TheTorProject/ooni-
 spec/blob/master/test-specs/ts-008-tcp-connect.md).

 Ideally this list should be easily generated (with the help of a script)
 and be accurate (up to date). The list currently lives on the ooni-
 resource repository:
 https://github.com/OpenObservatory/ooni-
 resources/blob/master/bridge_reachability/tor-bridges-ip-port.csv
