AnalyticDB for MySQL performs backend maintenance on clusters at irregular intervals to ensure cluster stability. Set the maintenance window to an off-peak period to minimize the impact on your workloads.
How maintenance affects your cluster
Before maintenance starts, AnalyticDB for MySQL notifies the contacts on your Alibaba Cloud account by text message or email.
During the maintenance window:
Not affected by default: database access, account management, database management, and IP address whitelist settings.

Make sure your application has both a retry mechanism and a reconnection mechanism.
