We do have multiple DNS servers at our primary data center and an
additional one at a remote data center so I think we are covered there in
terms of DNS redundancy.
I think a combination of entries in the /etc/hosts (all
application/database servers that make up that particular environment) and
DNS caching will take care of our issue. I think the caching may already
be set but perhaps the expire time is set too short. I'll work with our
Linux Admin to confirm this and get this straighten out.
I really appreciate all the great suggestions and feedback on this!
Thanks!

Hi Mark,
That can be configured in /etc/nsswitch.conf, on any Unix-like operating
system.
