>From what I gather, the customers involved are downstream from
branch.com, and as such a backup there doesn't seem to be serving much
purpose. In the two most probable scenarios of unreachability:
1. branch.com has connectivity problems with the world: The "backup" servers
aren't reachable either.
2. Customer has connectivity problems with branch.com: The hosts to be
resolved probably aren't reachable anyway.
When it is necessary to maintain a backup nameserver on a network
administered by someone else, and frequent changes are required for
maintenance of said nameserver, a system would be necessary to oversee
such changes. I don't think that this situation is widespread enough to
justify standardization. Most of our customers here have one or two
domains, and rarely, if ever, add more (excepting the in-addr hierarchy,
but since we assign them address space anyway, we can't unload that part
of the duty).
