    Network Shuts Down Safely                                          Workloads Routed via Switch Rails

Under an active-active failover configuration, both data centers process transactions simultaneously. If a primary facility experiences an unexpected crash, automated network switches route all processing workloads to the secondary remote center instantly, ensuring continuous system availability without manual intervention.
