I meant to say:

Configure all dns servers as secondary/slaves (one should be the primary master) for your own domains.  Thos means that all of your servers are authoritative for your own domains, so they cannot fail on local dns lookups due to Internet problems.

Ah!?

When I had it happen a couple years ago and wondered why even local names couldn't be resolved (which didn't make sense to me because the server would always know about them from the zone files), I was told that nothing could be done about it because DNS is designed to do lookups no matter what.

However, that was a server acting as both a local master and as a forwarder. If what you say is true, I would now understand this much better --- and I'd need to change my setup.
