+# Datacenters
+
+OpenStreetMap-derived datacenter features bundled for the local infrastructure
+layer.
+
+- Source: OpenStreetMap contributors
+- License: Open Database License (ODbL) 1.0
+- Feature count: 4,351
+- Runtime file: `datacenters.geojsonl`
+
+The public-release snapshot removes contact-oriented tags such as email, phone,
+fax, mobile, and WhatsApp values. The application does not display or depend on
+those fields; it uses feature identity, geometry, name, operator, and capacity
+metadata. The remaining derived database continues to be distributed under
+ODbL 1.0 with the required OpenStreetMap attribution.
+
+The original extraction date and query were not recorded alongside this
+snapshot. Future refreshes should record both before replacing the file.
