Try loading the URL in your own web browser and see if that loads up the ArcGIS Services Directory listing for that service. If it doesn't, then you probably have a URL problem.
Also, do you have a public facing link? If you post a public facing link, we could try to access it to see if it is correct on the public end.
The URL does not resolve. The error message states "This webpage is not available". Double check the URL to make sure it is correct. Then call map.addLayer(bound) after your declaration in your code above.
