We are excited to announce the preview release of maintenance windows for Azure SQL Database and Azure SQL Managed Instance.  Additional control and transparency into monthly maintenance events have been a common feedback from customers of Azure SQL Database and Managed Instance.  With the preview release of maintenance windows, you can now choose from predefined time slots for maintenance and set up alerts to be notified of upcoming maintenance events.

 

Gain more predictability with maintenance windows 

By default, all Azure SQL databases and managed instances are updated only during 5PM to 8AM local times daily to avoid any potential peak business hours interruptions.  During an Azure SQL maintenance event, databases are fully available but can be subject to short failover within availability SLA as resource reconfigurations are required in some cases. 

 

You can further adjust the planned maintenance events to a time suitable to your Azure SQL resource by choosing from two additional SQL maintenance window options.   

  • Weekday window, 10PM to 6AM local time Monday – Thursday
  • Weekend window, 10PM to 6AM local time Friday - Sunday

Once the maintenance window selection is made, all planned maintenance events will only occur during the window of your choice.

@scott_kim Looking forward to the functionality, although we've not noticed much around the maintenance in the night. But... we have a small data warehouse hosted on Azure SQL DB, with nightly processing. The maintenance windows are focused on the nights...

Yes, we are collecting feedback around desired windows and we aim to make additional options available over time.

 

Ability for customers  to configure windows is something that we are working on as well for certain offers.  please stay tuned for more updates towards summer but in meantime, please keep feedback coming.

thanks,

Can you please add some maintenance windows that are not covering the nights?

We have a UK based customer who's primary customer base comes online at 4pm and finishes around 12am in teh week days, and is active 9am -12am on weekends, so all 3 windows currently proposed are unsuitable.
We would need a window that is something like 2am-9am and set to weekdays.

This would also not be great for our other customers who have very restrictive maintenance windows.
