-IoT Hub provides Microsoft-initiated failover and manual failover by replicating data to the [paired region](../reliability//regions-paired.md) for each IoT hub. For some regions, you can avoid data replication outside of the region by disabling disaster recovery when creating an IoT hub.
+Azure IoT Hub provides Microsoft-initiated failover and manual failover by replicating data to a [paired region](../reliability/regions-paired.md) for each IoT hub. For some regions, you can avoid data replication outside of the region by disabling disaster recovery (DR) when you create an IoT hub.
 
 ## Prerequisites

+To disable DR in IoT Hub, you need the following requirements:
 
-* An Azure subscription. If you don't have an Azure subscription, create a [free account](https://azure.microsoft.com/free/).
-* The following regions support disabling disaster recovery:
-  * **Brazil South**; paired region, South Central US.
-  * **Southeast Asia (Singapore)**; paired region, East Asia (Hong Kong SAR).
