Regional failover mapping for Device Update for IoT Hub
In cases where an Azure region is unavailable due to an outage, Device Update for IoT Hub supports business continuity and disaster recovery (BCDR) efforts with regional failover pairings. During an outage, data contained in the update files submitted to the Device Update service may be sent to a secondary Azure region. This failover enables Device Update to continue scanning update files for malware and making the updates available on the service endpoints.
