Depends exactly what your "down" server is doing. If it's totally not
answering, the resolver at RR should silently fall back and try the =
other one.
It gets more interesting if your "down" server is still answering =
queries,
particlylarly if it's giving out "I never heard of it" answers with the
authoritative bit set because it's blown out a zone. In that case, the =
RR
resolver is within its rights to assume that your NS knows what it's =
talking
about and believing it.
