Manual Scaling

When using HireFire, we recommend against using Heroku's UI, CLI, or API to perform manual scaling operations on dyno types that are actively being autoscaled by a Dyno Manager (Autoscaler). The Dyno Manager caches the dyno formation of your application once every 15 minutes to reduce API calls to your account. This means that when you make adjustments to the dyno formation, the Dyno Manager will not be aware of these changes, resulting in incorrect autoscaling operations. The Dyno Manager will eventually correct this when its cache expires.

If you need to manually scale up or down, we recommend that you simply adjust the minimum and maximum dyno configuration of the Dyno Manager and let it scale up or down so that it can register this change.
