Exact Location of your SharePoint Online Microsoft Office 365 tenant

Quick answer: spin-up a few VMs in different Azure regions, then ping your SharePoint tenant. The moment you see 1ms ping you know the tenant exact location.

Full story

Microsoft says: “Customers should view tenant specific data location information in your Microsoft 365 Admin Center in Settings | Org settings | Organization Profile | Data location.
And it might look like:

That’s accurate to the geography (e.g. US, UE, AP), but not to the region (for instance – “Central US”, “UK West” or “Australia Southeast”).
In other words, If you know your data are in the US, you do not know where exactly – East/West/Central or South US.
Meantime when you create an Azure resource (e.g. Virtual Machine) – you can select specific region.

How do I know – where is my Microsoft 365 tenant actually located?

Can we just ping the tenant, analyze result and find Office 365 tenant region?
Luckily, SharePoint tenant is pinging with just
PS>ping tenantName.SharePoint.com
I have tested 5 regions and 4 different tenants:

ping from/to (ms)tenant 1 (US)tenant 2 (EU)tenant 3 (US)tenant 4 (US)
North Europe731796101
East US1833931
Central US221142323
West US631463633
South Central US3111211

So I figured it out:
My o365 tenants #3 and #4 regions are South Central US (Texas, San Antonio),
tenant #1 resides in East US.

Why do I need this?

Imagine you are running heavy reports against your tenant.
So probably you want your code running as close as possible to your tenant.
For this, you can spin-up a VM in Azure or use Azure Functions – just select proper region 🙂
