Regions
The Fly.io platform runs applications physically close to users: in datacenters around the world, on servers we run ourselves. You can currently deploy your apps in 26 regions.

* You can host your apps in any region; "Gateway" regions also have WireGuard gateways, through which you connect to your organization's private network.
** For some higher-demand regions we restrict scaling up VMs to organizations with paid plans.
Discovering Your Application's Region
You can see the list of Fly.io regions any time with fly platform regions.
You can see which regions your app is running in with fly status.
Fly.io storage volumes are tied to the region they're created in.
When an application instance is started, the three-letter name for the region it's running in is stored in the VM's FLY_REGION environment variable. This, along with other Runtime Environment information, is visible to your app running on that instance.
