The maintenance window controls when the backend system performs maintenance on your ApsaraDB RDS for MariaDB instance to ensure its stability. Set the window to off-peak hours to minimize disruption to your workloads. The default window is 02:00–06:00.
Before the maintenance window starts
-
Email notification: Before maintenance begins, the system sends emails to the contacts associated with your Alibaba Cloud account. Check your inbox regularly so you can prepare in advance.
-
Instance state change: The instance enters Maintaining Instance state before the window opens. In this state:
-
Database access and query operations (including performance monitoring) continue normally.
-
Account management, database management, and IP address whitelist configuration remain available.
-
Upgrade, downgrade, and restart operations are temporarily unavailable.
-
-
Transient connections: One or two transient connections may occur during maintenance. Configure your application to automatically reconnect to the instance.
