<p>Well as far as I know we were only using jsonp because XHR wasn't possible - we certainly prefer not to use it. Is there a suitable cross domain policy in place that will allow access?</p>
<p>Also you will need to update <a href="https://github.com/openstreetmap/openstreetmap-website/blob/master/app/controllers/application_controller.rb#L411">https://github.com/openstreetmap/openstreetmap-website/blob/master/app/controllers/application_controller.rb#L411</a> to move graphopper from <code>script_src</code> to <code>connect_src</code>.</p>
