A and AAAA type DNS records can be setup for automatic DNS failover at DurableDNS. DurableDNS will monitor your server and if it becomes unavailable the DNS record can be changed to a backup server automatically. DNS failover can be used with round-robin DNS and DNS load balancing to distribute traffic to two servers when both are online and to one server if the other fails.
