What does this have to do with Web servers?

To what "domain name configuration" are you referring? The domain 
registrar? If so of course, redundancy is always good.

One of those two (or a third "stealth" nameserver) will be the master 
for the zone. The other (or both, if there's a stealth master) will 
receive "notifies" from the master when the zone is changed. It then 
comes and initiates an IXFR.

Servers with good connectivity can accomplish this in under 1 second; 
both will be serving the same data for the zone. Of course old queries 
will still be cached until the TTL expires.
