DNS Failover keeps sites and web services online in the event of system or network issues. This is done by moving DNS traffic
from one IP address to another IP address that you have running at another location.
Failover is most commonly used to move traffic off of an unhealthy web server, and redirect it to a preconfigured backup web
server.
DNS Made Easy’s failover service has a fifteen-year history of keeping domains online guaranteed. Past studies have revealed
that DNSME failover saved businesses an estimated
$525 million in revenue
in one quarter alone.
Failover uses health checks to monitor the status of the IP address(es) in your records. Health checks run every 2-4 minutes from
multiple monitoring locations.
A failover event will only occur if two of our monitoring nodes report your primary IP address as down. In that case, we will run a
quick health check for your first backup system. If it is available, we will update the record to point to your first backup IP
address.
If that one goes down, we’ll check the second backup system and update the record. You can set up to four backup IP addresses in a
failover record.
We will continue to monitor your primary endpoint, even after a failover event has occurred. When it comes back online, we will
automatically “failback” traffic to your primary.
