I'm opening this ticket to not forget a project we should push forward soon.
The ambassadors map is not really working anymore, but it was also created many years ago. It would be nice to start doing something for the upcoming hubs, and as long term project we could aim to reproduce the map mozilla is using.
In the meanwhile, why we don't create a KML file of our ambassadors and use it on a map we can easily port to the Hubs? As a starting point it might be enough, the script could be hosted here in this repo.
