Regions

The three regions, na, eu and ap; where sandboxes, Cubes and Drives are made; what happens when a region cannot take something; and how traffic is priced by region.

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.

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).

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

Traffico in uscita verso internet, in base a dove esce Prezzo
Nord America $0.004 per GB
Europa $0.004 per GB
Asia-Pacifico $0.01 per GB

Traffic to the internet is priced by the region of the machine it leaves from. See pricing and plans.

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.
