Instance launches triggered by shutdown hours
If you use shutdown hours and autoscaling is disabled, Ocean does not scale up new nodes for pending pods. However, Ocean may still launch an existing node in two situations:

• When the shutdown hours period ends

• When the node that launched at the end of shutdown hours experiences an interruption or recovery event

In these cases, Ocean may show one of these messages in the console:

Info Instances: [i-xxxxx] have been launched. Reason: Shutdown hours period finished 
Info Instances: [i-xxxxx] have been detached. Reason: Scale-down as part of instance recovery
Info Instances: [i-xxxxx] have been launched. Reason: Scale-up as part of instance recovery



How to stop this behavior
If you want to prevent these launches, disable shutdown hours in the Flexera console:

1. Go to Ocean.

2. Open Cloud Clusters and select your cluster.

3. Select Actions.

4. Choose Customize scaling.

5. Select Cluster shutdown hours and disable the setting.
