Wanted to share quick trick on how to detect where your M365 tenant is hosted. Simply open URL below with tenant URL in the middle. Response JSON contains property “tenant_region_scope”:”NA” showing the physical host location. Cheers.
NOTE – For tenants hosted on GCC or you will see an extra property “tenant_region_sub_scope”:”GCC”
