Managed Kubernetes will start to align the resources in the target data center. In case you have selected a new version for Kubernetes, the operation may take a while, and the node pool will be available for further changes once it reaches the **Active** state.

**Note:**

* Avoid accessing the target data center while Managed Kubernetes is provisioning nodes, as concurrent manual interaction can cause undesirable results.
* The **maintenance window** starts at the time of your choice and remains open for the next four hours. All planned maintenance work will be performed within this window, but not necessarily at the beginning.
