Azure Resource Health overview

Azure Resource Health helps you diagnose and get support when an Azure service problem affects your resources. It informs you about the current and past health of your resources. And it provides technical support to help you mitigate problems.

Whereas Azure Status informs you about service problems that affect a broad set of Azure customers, Resource Health gives you a personalized dashboard of the health of your resources. Resource Health shows you all the times your resources were unavailable in the past because of Azure service problems. It's then simple for you to understand if an SLA was violated.

Resource definition and health assessment

A resource is a specific instance of an Azure service: for example, a virtual machine, a web app, or a SQL database.

Resource Health relies on signals emitted by the different Azure services to assess whether a resource is healthy or not. If a resource is unhealthy, Resource Health analyzes additional information to determine the source of the problem. It also identifies actions that Microsoft is taking to fix the problem or the actions that you can take to address the cause of the problem.

For additional details on how health is assessed, review the full list of resource types and health checks in Azure Resource Health.

Health status

The health of a resource is displayed as one of the following statuses.


A status of Available means that the service hasn't detected any events that affect the health of the resource. In cases where the resource has recovered from unplanned downtime during the last 24 hours, you see the Recently resolved notification.

Status of "Available" for a virtual machine with a "Recently resolved" notification


A status of Unavailable means that the service has detected an ongoing platform or non-platform event that affects the health of the resource.

Platform events

Platform events are triggered by multiple components of the Azure infrastructure. They include both scheduled actions (for example, planned maintenance) and unexpected incidents (for example, an unplanned host reboot).

Resource Health provides additional details on the event and the recovery process. It also enables you to contact support even if you don't have an active Microsoft support agreement.

Status of "Unavailable" for a virtual machine due to a platform event

Non-platform events

Non-platform events are triggered by users' actions. Examples are stopping a virtual machine or reaching the maximum number of connections to an Azure Cache for Redis.

Status of "Unavailable" for a virtual machine due to a non-platform event


The health status of Unknown indicates that Resource Health hasn't received information about this resource for more than 10 minutes. Although this status isn't a definitive indication of the state of the resource, it is an important data point in the troubleshooting process.

If the resource is running as expected, the status of the resource will change to Available after a few minutes.

If you're experiencing problems with the resource, the Unknown health status might suggest that an event in the platform is affecting the resource.

Status of "Unknown" for a virtual machine


The health status of Degraded indicates that your resource has detected a loss in performance, although it's still available for usage. Different resources have their own criteria for when they specify that a resource is degraded.
