featuredatagrid sample broken?

[KirkKuykendall]

When I go here:
http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#FeatureDataGrid

I don't see any graphics on the map when I click.

Fiddler shows this query going out:
http://serverapps.esri.com/ArcGIS/rest/services/California/MapServer/8/query?returnGeometry=true&spa...

When I run it, it returns:
{
  "error" :
  {
    "code" : 400,
    "message" : "",
    "details" : [
      "Unable to perform query. Please check your parameters."
    ]
  }
}
Has the REST API changed (1=1 seems like it could kill some servers)?

I think the map service is not available: http://serverapps.esri.com/ArcGIS/rest/services/California/MapServer/8.

Not sure why serverapps.esri.com went down last Friday, but it's been up now since Friday evening without incident.   We'll keep an eye on it.
