The Planned Maintenance pane in Azure Service Health is a dedicated section in the Azure portal that keeps you informed about upcoming maintenance activities. It highlights events that can affect your Azure resources, helping you prepare in advance.
Here's a breakdown of its purpose and the information it provides:
This pane is designed to provide you with advance notice of scheduled maintenance events that can affect your services. The information enables you to:
- Prepare for possible service disruptions
- Coordinate internal change management processes
- Use self-service update windows when available
Unlike unplanned outages, planned maintenance is scheduled and communicated ahead of time to help minimize the effect.
Get started with Planned maintenance
When you open the Planned maintenance pane, you see a list of maintenance events relevant to your subscriptions.
On the main panel you can sort the displayed list of Planned maintenance events by Scope, Subscription, Region, Service, and Event tags.
There are options to:
- Create a service health alert
- Download the events as a CSV file
Each event includes the following information:
- Issue Name
- Tracking ID
- Services
- Regions
- Start time
- End time
- Last updated
- Event tags
Select the Issue name link to open the tabs with the information you need.
Note
Planned maintenance events are displayed in the panel for 90 days if they are still active and if the impactMitigationTime/endtime is set in the future. After that they are moved to the health history panel where they are displayed for 90 days.
For more information about Planned maintenance events using ARG queries, see:
