We are pleased to announce the Public Preview of Maintenance Window Management in Power Platform Admin Center!
Not all customers operate within the strict definition of day-time business hours; shifting the Maintenance from the default settings today to a time that best suits business needs for a given Environment will lend customers desired flexibility in scheduling Application and Database updates.
Please note Maintenance windows are not intended to signal downtime. We offer an online platform where customers can run mission critical applications/workloads 24×7, all the while bringing new value frequently without incurring any downtime or performance degradation. Maintenance windows allow customers to make sure that any perturbations to the service, even though done in a fully online fashion, can happen only during the configured time window.
For more information on the types of activities in scope of this feature and how to utilize it, please refer Maintenance Window Management docs
