+This section describes some of the important aspects of how the service works that are most relevant from a reliability perspective. The section introduces the logical architecture, which includes some of the resources and features that you deploy and use. It also discusses the physical architecture, which provides details on how the service works under the covers.

+- **Notification**: Microsoft doesn't automatically notify you when a region is down. However, you can use [Azure Service Health](/azure/service-health/overview) to understand the overall health of the service, including any region failures, and you can set up [Service Health alerts](/azure/service-health/resource-health-alert-arm-template-guide) to notify you of problems.
