Yes, our DNS failover service was designed to easily support manual failover. Often customers wish to test their failover site on a periodic basis, or they wish to redirect traffic during a maintenance window.
To do this within the portal, open up the Failover Entry, and simply uncheck the “Active” checkbox as shown below. This will immediately take the device out of service and send traffic to the device with the next highest priority (sequential mode) or all remaining online devices (round robin mode). But before you do that, make sure one of your other devices is green and active and ready to take the traffic!
When you’re done, simply check the active box again.
