# Region Optimization

Vagon maintains a pool of pre-warmed machines in high-traffic regions to minimize connection times for all users, regardless of whether they use the Cost Optimized method. These pre-warmed resources are available to all Vagon users without requiring a [Premium Feature Plan](https://docs.vagon.io/streams/configurations/premium-feature-plans).

When Region Optimization is enabled, the system prioritizes assigning a pre-warmed machine based on the user's physical location. It first checks for available pre-warmed machines in the selected main region(s). If a pre-warmed machine is available in the user's primary region, it is immediately assigned to the user.

If no pre-warmed machines are available in the primary region(s), Vagon checks predefined satellite regions. If a pre-warmed machine is available in a nearby satellite region, it is immediately assigned to minimize connection time for the user.

If no pre-warmed machines are available in either the main or satellite regions, Vagon automatically provisions a regular machine in the user's main region.

A daily data center fee will be applied if the system assigns a Stream Machine from a satellite region.
