Hello @Pascal ,
By definition on a search in the web:
"Non-regional services: Services that don't depend on a specific Azure region, making them resilient to zone-wide outages as well as region-wide outages."
See: https://azure.microsoft.com/en-us/global-infrastructure/services/?products=azure-maps
By that, you aren't in control on what server serves your application (this is Azure internals). Are you experiencing high latencies? Can you develop more on what you are trying to achieve?
Thanks.
