For DNS it's recommended to just have multiple nodes which are all active, or use a networking technique such as anycast, bgp-ondemand route advertisement, or even better a dns aware load balancer such as dnsdist to perform failovers if you want to have an active / standby setup.</p></div><div><p class="MsoNormal"> </p></div><div><p class="MsoNormal">I hope this answers your question.
