Suggested rule

Azure periodically performs planned maintenance of SQL Database resources. During a maintenance event, databases are fully available but can be subject to short reconfigurations within availability Service Level Agreements (SLA) for SQL Database).

By configuring a customer-controlled maintenance window, you can schedule updates to occur during a preferred time, ideally outside business hours, minimizing disruptions.
