Summary

Documents the requirements that custom GeoJSON URLs must satisfy when used in area (choropleth) maps, so users can troubleshoot URLs that fail to load.

Changes

  • Added a "Custom GeoJSON URL requirements" subsection to the area maps page covering HTTPS, file extension, size and timeout limits, public-address requirement, and the no-redirects rule.

Context

The upstream change tightened the server-side proxy that fetches custom GeoJSON files: it now validates the resolved IP against a broader set of private/reserved ranges, pins the connection to a pre-validated address to prevent DNS rebinding, and rejects redirects outright. These are user-visible constraints — previously valid URLs that redirect or resolve to private/CGNAT space will now fail — so they are worth surfacing in the map documentation.
