Onion services are the .onion addresses of services hosted by TPA,
otherwise accessible under .torproject.org.
This service is gravely undocumented.

Descriptor unreachable
The OnionProbeUnreachableDescriptor looks like:
Onion service unreachable: eweiibe6tdjsdprb4px6rqrzzcsi22m4koia44kc5pcjr7nec2rlxyad.onionIt means the onion service in question (the lovely
eweiibe6tdjsdprb4px6rqrzzcsi22m4koia44kc5pcjr7nec2rlxyad.onion) is
currently inaccessible by the onion monitoring service,
onionprobe.
Typically, it means users accessing the onion service are unable to access the service. It's an outage that should be resolved, but it only affects users accessing the service over Tor, not necessarily other users.
You can confirm the issue by visiting the URL in Tor Browser.
We are currently aware of issues with onion services, see tpo/tpa/team#42054 and tpo/tpa/team#42057. Typically, the short-term fix is to restart Tor:
systemctl restart torA bug report should be filed after gathering more data by setting the
ExtendedErrors flags on the SocksPort, which give an error code
that can be looked up in the torrc manual page.
For sites hosted behind onionbalance, however, the issue might lie elsewhere, see tpo/onion-services/onionbalance#9.
