NS_ALL_UNREACHABLE

error

None of this domain's nameservers answered, so nothing under this name resolves for anyone.

Something is wrong and mail or certificates are affected.

How we know

test
Delegation faults that need no zone of their own: a single-nameserver delegation is every other zone here, and the two total-failure codes are reached by pointing the evaluator at a server that is not there rather than by publishing a broken zone nothing else could use.
