This question might be more suitable for inet-access, but it's down, so
I'm resending here:

Silly question:

If you have a customer who is doing their own primary DNS, but you are
doing their secondary DNS (on 2 of your name servers) for them, is it
better practice on your 2nd DNS server to xfer the zones directly from the
customer's primary DNS server (a second secondary DNS server) or xfer it
from your first server (the customer's secondary server) doing "true
tertiary" DNS?  Or should the tertiary use multiple masters?
My hobbiest setup pulls from multiple masters. Not much point having multiple
servers if a little network partitioning (which happens all too often) will stop your servers from communicating.
