The link works for me. It’s a pretty short JSON so I posted it below:

{
  "tilejson": "2.1.0",
  "format": "heightmap-1.0",
  "version": "1.1.0",
  "scheme": "tms",
  "tiles": ["{z}/{x}/{y}.terrain?v={version}"],

You can also look at the CesiumTerrainProvider source to see what it’s doing with the availability and all that:
