[cobalt-users] dns and nameservers

["Jim Carey" <ozbcoz@xxxxxxxxxxxxxxxx>]

Hi,

I currently have my DNS on 1 server (bad I know). I have just agreed a
secondary service with someone else in a different geographic region. I will
be asking customers to add this secondary nameserver onto their delegations.
What I want to do is to simply ask them to add this new one on as an extra
(ie 3rd nameserver).

So I will have

web.ozdns.net
web2.ozdns.net
new.nameserver.com

as the recommended suite.

Now web.ozdns.net and web2.ozdns.net are both on the same server. Is this an
issue in terms of performance or reliability - if say the web.ozdns.net
facility is temporarily unavailable and this is the one that has been tried
first then it will go for one of the others (yes ?) - if it happens to pick
web2 then if that is still unavailable it will go to the new.nameserver.com
(yes?). If that's the case the worst that should happen is a small amount of
additional delay while it cycles through the two ozdns.net nameservers.

(problem is that I restart named every 30 minutes to pick up new domain
names for my redirect service and sendmail every 60 minutes to pick up new
email redirects - so there are bound to be times when a query won't find the
ozdns.net nameservers)

cheers and a very happy Easter to all out there :-)
