If you use Community Hub then you are familiar of spinning up TrialForce orgs for whatever reason. My use has been spinning up TrialForce orgs for demoes and training purposes.

When I spin up TrialForce orgs they are created on the US nodes. But what if you want the TrialForce org spun up on an EU node or Asia node?

The solution is simple.

A TrialForce org will be spun up on the region specified based on the User’s locale making the request. So, if I wanted a TrialForce org on a EU node at the user level change the locale of the user to a country in Europe. Then create/request a TrialForce org from Community Hub.
