Abstract
Active-active standby is maintained for communication sessions using web connections between two active session zones and a standby session zone, for example, in the event of a failure. The first active session zone is located at a first datacenter, the second active session zone is located at a second datacenter, and the standby session zone is located at a third datacenter. In the event of a failure at a first active session zone at the first datacenter, a failover to the second active session zone at the second datacenter is performed. In the event of a failure at both active session zones, a failover to the standby session zone at the third datacenter is performed.
