I am working on creating an application that uses a geocode service to locate and plot the location of a given address. I was trying to follow the sample provided here: http://help.arcgis.com/en/webapi/javascript/arcgis/samples/locator_address/ but it does not seem to be working. It works some of the time, but other times the service hangs and does not give any results. Is this there a problem with the geocoding service?
