Why not mirror the hosts, give them both 1 virtual IP
and put them behind a Local Director, or home-made
Linux equivalent? That way, you can load share, and
if one RaQ fails, the Director will take the failed
RaQ box out of the loop and direct all of your queries
to the good RaQ.

Subject: [cobalt-users] [RAQ] Redundant Servers
Hello Everyone-
I am trying to run through a scenario with 2 RaQ servers. RaQa is the
home of the site (testing.com) and the primary DNS server. RaQb is the
home of the secondary nameserver. Normally I would just set a DNS entry
in RaQb for secondary nameservice for testing.com. Now if RaQa goes
offline the site goes down, but it does not give the DNS record not
found error.
What if I did this. Instead of adding a secondary nameservice record in
RaQb I created a site identical to the one on RaQa. Named it the same
and put it on an IP resolving to RaQb. Then created A records for
testing.com to point to that IP address.
Heres the Question:
Now if RaQa goes down since the secondary nameserver routes the site to
a different IP will the site come up on RaQb?
Thank you,
Dennis
