Comment (by gk):

 The exit policy of that relay is sufficiently broken that it should not be
 used as exit (I pinged the operator and will badexit the relay early next
 week if I don't hear back), however it's not clear yet why check actually
 thinks it's the case.

 [https://github.com/NullHypothesis/exitmap/blob/master/src/modules/checktest.py
 `checktest.py`] is pretty close to what `exitscanner`
 [https://gitweb.torproject.org/metrics-cloud.git/tree/ansible/roles/exit-
 scanner/files/ipscan.py is using]. However, as the error message in the
 description clearly shows the exit *is* able to resolve
 `check.torproject.org` (thus, the exit policy is acceptable for that
 particular test at least. Or maybe that's only holding for most of the
 cases when `check.torproject.org` resolves to `116.202.120.181`?). Thus,
 it is not obvious where the `"IsTor":false` is coming from.
