Comment:

 This issue appears intermittently: all the tests work for me sometimes,
 other times some fail.

 People who have this issue should try the latest chutney master
 (>=3a3c1d5).
 It fixes 2 potential causes for this issue: #20409 and #22134.

 A third potential cause is fixed in #21903 in my branch no-dns-rebased,
 but we're waiting for feedback on tor-dev before merging it to master.

 But I think the issue is actually how we do HSDir fetches in small
 networks.
 There's no way we should try the same relay twice in the same second.
 And we shouldn't call it failed if we do.

 This seems like another instance of the "6 quick onion address requests
 fail" issue. (I can't find the older ticket right now.)
