Hi,
I'm an app services support engineer in Microsoft CSS.

Received a customer case where they were anxious and confused about the cool down period behavior causing unexpected scaling actions (2508220050001316).

Adding this clarification to the Microsoft docs will help prevent such confusion and support requests by clearly explaining when and how the cool down period works in Azure Container Apps scaling.

**Note:** The KEDA cooldownPeriod only applies when scaling down to 0 instances and is not enforced for scale-down operations where the number of replicas decreases from N to a value greater than 0; whereas scaling up from 1 to N replicas is managed by the Kubernetes Horizontal Pod Autoscaler.
