Recently, when I open pages with multi-region maps, the dinamic map fails to load, only the static fallback image is shown. The Kartographer extension tries to load GeoJSON for each regions, but some of them are rejected by the server 'maps.wikimedia.org' with response '429 Too Many Requests'.
It can be easily reproduced on the following pages:
Possible solutions are:
# Configure the map server to allow more mapshape requests per client at once.
# Implement some caching mechanism to reduce the number of requests, and reduce load.
