For identifying Azure services within your tenant that're deprecated, have ongoing service issues, upcoming planned maintenance, or relevant health advisories - in the scenario where you miss communication, you can leverage Azure Service Health. Service Health provides you with a customizable dashboard which tracks the health of your Azure services in the regions where you use them.
Service Health tracks four types of health events that may impact your resources:
- Service issues - Problems in the Azure services that affect you right now.
- Planned maintenance - Upcoming maintenance that can affect the availability of your services in the future.
- Health advisories - Changes in Azure services that require your attention. Examples include deprecation of Azure features or upgrade requirements (e.g upgrade to a supported PHP framework).
- Security advisories - Security related notifications or violations that may affect the availability of your Azure services.
