isochrone demo broken

[meetar]

Followed link at the bottom of https://mapzen.com/blog/introducing-isochrone-service/ to https://valhalla.github.io/demos/isochrone/ – clicking on the map returns a 403 forbidden error, nothing else happens.

It's possible this is a dupe of https://github.com/valhalla/demos/issues/204
