A map of all ~2,100 Swiss municipalities, grouped by jurisdiction. Each is colored by the provider handling its official email, based on public DNS records and other public network signals.
Context
-
Digital sovereignty: US-based providers are subject to the US CLOUD Act, which allows US authorities to request stored data, regardless of where it is physically hosted. This map makes the current provider landscape visible.

How does it work?
-
Each municipality's official domain is checked via 11 signals from DNS records, SMTP banners, ASN lookups, and a public Microsoft API endpoint, then classified by provider type with confidence scoring.

Disclaimer: DNS records indicate mail routing and authorized senders, not necessarily where data is stored.

M365 Tenants of Swiss Municipalities
-
-
-
What is this?
-
A map of all ~2,100 Swiss municipalities showing whether their official domain is registered as a Microsoft 365 tenant — detected via a public Microsoft endpoint.
-
-
-
What does a tenant mean?
-
A registered M365 tenant means the municipality's domain is in Microsoft Entra ID, implying (but not confirming) the use of M365 services such as Teams, SharePoint, or OneDrive — but not necessarily email. See the Email Map for email hosting.
-
-
-
Methodology
-
Each domain is queried against Microsoft's public getuserrealm.srf endpoint (unauthenticated). It returns: Managed (fully cloud-managed identity), Federated (hybrid, on-premises AD synced to cloud), or no result.
-
Caveat: Tenant presence confirms domain registration, not specific service usage. Some tenants could be inactive.
