* You can host your apps in any region; "Gateway" regions also have WireGuard gateways, through which you connect to your organization's private network.
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.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.
