If the fedora NS had returned SERVFAIL or if it was not reachable,
your company's NS WOULD have tried another fedora NS.

If the fedora NS indeed returned NXDOMAIN or an authoritative NO ANSWER
that name server was telling your company's NS that it was certain that
the requested domain did not exist.

They were broken and your company's NS behavior was exemplary.

HTH,
