May I ask what is the platform that you implement the server build?
To be clear , the server won't turn back to "Standby". When the application quits, the instance will shutdown and it means the lifecycle of an instance has ended (each instance is unique), the resources (server cores) will be released and back to the resources pool. When the number of Stand-by servers is less than the configuration in the Game Manager, PlayFab will dynamically initialize it, no matter how many live titles or any instances are shutting down.
