A cluster maintenance window is a period during which system updates are allowed. There are three available options:

-   Never
-   Any time
-   Specific time

During the maintenance window, certificates may be updated, and security patches may be installed. Updates can affect both master and worker nodes. During this time, operations on the cluster will be blocked. Short service interruptions may occur, for example, during node restarts.

You can set the maintenance window when creating a cluster, and you can manage it later in the cluster settings.

To change the maintenance window:

1.  In the **Kubernetes** section, click on the cluster.
2.  On the **Management** tab, click **Change** next to **Cluster maintenance window**.

3.  Select the preferred maintenance window and save the changes.
