You can change the cloud provider region through which your federated database instance requests are routed. By default, Data Federation requests are routed through the region that is closest to your client application. The region that is closest to your application may be different from the regions that house your data stores.
Note
If you change the cloud provider region through which your federated database instance requests are routed, you must update your federated database instance connection string with the new hostname. This change ensures that your requests are routed through the new region.
Required Access
To update your federated database instance region, you must have Project Owner access to the project. Users with Organization Owner access must add themselves as a Project Owner to the project before setting up a private endpoint.

The closest available region to allow Atlas to automatically choose the Data Federation region closest to you.
A specific region to specify the region through which your federated database instance requests must be routed.
Click Save for the changes to take effect.
The federated database hostname in your current federated database instance connection string will continue to work. However, to use the region you selected, you must update the federated database hostname in your federated database instance connection string. To utilize the new region, click the Connect button for your federated database instance and follow the steps in Connect to Your Federated Database Instance.
