 # MXmap — municipal email infrastructure maps
 
+> [!IMPORTANT]
+> **MXmap has a successor.** This project grew into a team research effort covering all municipalities in Germany, Austria and Switzerland: **[secassure2026.mxmap-project.org](https://secassure2026.mxmap-project.org/)** ([source](https://github.com/mxmap/secassure2026)). The Swiss map at [mxmap.ch](https://mxmap.ch) stays online, but its data is frozen as of April 2026 and will not be updated.

 Interactive maps showing where Swiss municipalities host their email and how deeply their DNS is tied to US hyperscalers (Microsoft, Google, AWS) versus Swiss providers and self-hosted solutions.
