If you don't want multiple DNS server entries on the client

I'm ok with them, only the problem is that the clients take their timeouts when a server is unreachable, and users panic.

On Linux systems, you can set the timeout in /etc/resolv.conf, e.g.,

# I think the default nameserver timeout is 5; use rotate # option if you prefer round-robin queries rather than # always using the first-listed first nameserver 10.11.12.13 timeout:2 rotate nameserver 10.11.12.14 timeout:2 rotate

I'll admit that I'm not sure if those options are configurable on Mac and/or Windows workstations.
