Failover is a DNS record setting that allows you to specify backup IP addresses or hostnames that are only used when the primary IP/hostname is unavailable. It is considered to be the most affordable type of DNS load balancing.
Use Failover to add redundancy to your mission-critical services, such as mail or VoIP systems.
Constellix supports Failover for A, AAAA, ANAME, and CNAME records.

Our load balancing services range from basic Round Robin with Failover to latency-based routing. All of these services are fueled by our monitoring service and use health and latency metrics to update your DNS configurations.
