On the grounds that paranoia is clearly better, my suggestion at this point
would be to run tcpdump between the caching resolver and ntpd and see what is
actually going on the wire. The name server should be rotating them in reply,
and it would be good to confirm that it's doing that. It would also be good
to check that it's looking up what you think it's looking up, and indeed, what
it should be looking at.
