Tried setting up a CesiumTerrainProvider this morning and kept getting the following error:

XMLHttpRequest cannot load [http://assets.agi.com/stk-terrain/world/layer.json](http://assets.agi.com/stk-terrain/world/layer.json). No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '[http://localhost:8080](http://localhost:8080)' is therefore not allowed access. The response had HTTP status code 503.

I even attempted to look at the terrain in Sandcastle on the Cesium website, which also does not work:

> **[Cesium Sandcastle](https://sandcastle.cesium.com/index.html?src=Terrain.html&label=Showcases)**
>
> The Cesium Sandcastle provides an interactive environment for testing Cesium code.

When you load the terrain sandcastle it appears as if there is no globe, but if you zoom out far enough you'll see a transparent globe and an error in the console about a problem loading the terrain.

Is this being looked into?

Thanks for the report. We are already looking into it and it should be back in no time.
