Depend how often you change DNS records, but normally 2-3 days IMHO is OK

Hi,
what is the TTL of your DNS records ? After TTL expires, the slaves don't respond to queries either, because the records aren't valid anymore. If your primary is down longer than the TTL of your DNS records you could reconfigure one of the slaves as a new primary or maybe consider making more than 1 primary.

Have you describe all the slave servers in you domain configuration (in registrant)?

Hi,
I have 4 bind9 dns installed on centos 4. My primary dns server went down and all of my domains doesn't resolve even if the 3 slave dns is up and running. Im not sure where to configure this is it in my domain registration or in bind?
