Configure GTD with DNS Failover

Solution ID : SO122
Last Modified : 10/21/2023

The Global Traffic Director gives clients the ability to geographically respond to queries differently based on region. It is useful as you have multiple different servers located around the world and you want to direct your traffic to the closest server.
For example, you can have your ‘www’ record for your domain point to a web server at in Asia and a different webserver at in the United States on the west coast. Querying clients in the Asia region are sent to while US querying clients are sent to We also have two additional servers set up at in the United States on the east coast and as the default IP.
This is what we will configure below for example-1.com. We will also configure DNS Failover service on the Asia and US West Coast A records so in the event that in Asia is offline, all traffic will be sent to the United States West Coast (the next closest geographical region) and in the event in the United States West Coast is offline, all traffic will be sent to the US East Coast (the next closest geographical region).
