I don't think so. I've a lot of experience with DNS, from X-emulations,
Windows NT, NFS access, remote boot etc. BUT all grab the first ns the find
and when this ns dies, the wait till they are dead (aka enormous
timeouts!). Never seen a failover to a second.
The second ns will only be used when the first is dead when the app come up!
