I am looking for documentation on HA pair failover times..I think the failover for an HA pair is 5 seconds plus...


I have a customer with a <1 second DNS failover requirement. How do i get to this number for failover?

The active and passive node of an Infoblox HA pair grid member send VRRP hello packets every second. When the passive node does not receive 3 consecutive VRRP packets it will think that there is a problem with it active node and it will try to become active , so if there is an issue with the active the passive node will take over in a 3-4 second timeframe.


An Infoblox HA pair is used for hardware redundancy and not for service redundancy.


If you have a best practises Grid infrastructure with primary and secondary DNS grid members and you configure/provide you DNS clients with multiple DNS servers then the DNS clients will not encounter a DNS failure if one or even mutiple DNS grid members would have an outage.
