DNS Failover

Load balancing and health checking.

Easily integrate health checks into your load balancing configurations with baked-in Failover. Failover automatically moves your traffic from unavailable resources to healthy ones. The most affordable and easiest type of load balancing to configure.

Failover is supported for A, AAAA, ANAME, and CNAME records. All you need to do is enable Failover for your record, and specify the IP addresses or hostnames of your backup resources. These backups are only used when the primary IP/hostname is unavailable.

Why do I Need DNS Failover?

The main reason you would want failover enabled in your DNS solutions is to prevent an outage and keep healthy traffic to the most reliable sources. DNS outages can occur for a multitude of reasons like DDoS attacks, configuration errors, or faulty equipment. If your organization has experienced an outage, you know the overall severity it can have on your business. The downtime can cost you thousands in lost revenue, and the hundreds of employee hours doing damage control really starts to add up.
