# Regions

There are three regions:

| Region | Where |
|---|---|
| `na` | North America |
| `eu` | Europe |
| `ap` | Asia-Pacific |

Which regions are open, and how each one stands, is on the [status page](https://glac.ai/status/).

## Where things are made

| What | Where |
|---|---|
| A sandbox | The `region` of `POST /v1/sandboxes` or `POST /v1/run`; without one, the region of the API you call. |
| A Cube | Every region in its `regions` (all three unless you say). A request is answered in the region it comes in at. |
| A keyed instance | The region of the edge its first request came in at, or the `region` of `POST /v1/apps/{app}/instances`, among the app's regions. |
| A Drive | The `region` of `POST /v1/drives`; without one, the region of the API you call: its home. A sandbox of another region mounts it too where that region's machines read its home's object store, and its home follows it there after an hour ([across regions](/docs/drive/concepts/#across-regions)). |

A sandbox's and a Drive's `region` say where they are. A keyed instance's label `metadata.region` says where it was asked for: the two differ when it had to be made elsewhere (below).

## When a region cannot take it

A new sandbox goes to the region it asks for while a machine there can take it. When none can (none is there, all are full, none has room for its size), it goes to the next region that can, nearest first: from `na` to `eu`, then `ap`; from `eu` to `na`, then `ap`; from `ap` to `na`, then `eu`. A sandbox that must be on one machine (made from a snapshot that only that machine has, or with a volume of that machine) goes there, whatever its region.

A Cube's request goes to a machine of its region that serves the app; another region takes it only when no machine there can.

## Traffic out, by region

| Traffic out to the internet, by where it leaves from | Price |
|---|---|
| North America | $0.004 a GB |
| Europe | $0.004 a GB |
| Asia-Pacific | $0.01 a GB |

Traffic to the internet is priced by the region of the machine it leaves from. See [pricing and plans](/docs/platform/pricing/#traffic-out-by-region).

## Not there yet

- Mounting a snapshot of a Drive read-only in another region than the one it was taken in.
- A separate address of the API in each region: today one API answers for every region, and things made without a `region` are made where it is.
