Failover example

In this example, there are two data centers, one in New York and one in Los Angeles. The New York data center is the primary data center. It has one server in it with IP address 192.0.2.0. The Los Angeles data center is the backup. It has one server in it with IP address 192.0.2.1. The property name configured is failover, so the fully qualified domain name is failover.customer.akadns.net.

Global Traffic Management periodically tests both servers for liveness. As long as the liveness test for the primary data center is succeeding, DNS queries for failover.customer.akadns.net will return an A record for 192.0.2.0. However, if the liveness test for the primary data center fails, DNS queries returns an A record for the backup server, 192.0.2.1.
