How can I determine customer data location?

We are in the process of updating the actual data location in Tenant Admin Center. When this change is complete the tenant will be able to see the actual data location, for in scope data, by navigating to Admin|Settings|Org Settings|Organization Profile|Data Location. Until that change is visible, you can view the Exchange Online data or SharePoint Online location information in order to understand where the in scope data is stored for this service.
