Device Registry is a single-region service. If the region becomes unavailable, your Device Registry resources are also unavailable.

However, if your resources are in a [region that's paired](./regions-paired.md), your registry's data is replicated to the paired region.

In the event of a prolonged region outage, Microsoft might elect to fail over to the paired region. If this happens, your registry continues to be available in the paired region.
