A fault location system (FLS) for a hybrid fiber coax (HFC) cable network. The FLS comprises an interactive map, a datastore, an object generator, and a display server. The datastore receives identifying information and status information of customer premises equipment (CPE) units connected to the HFC cable network. The object generator associates the identifying information and the status of CPE units with an object and further associates graphical attributes with the object. The display server graphically displays the object on the interactive map at location coordinates indicative of the street address, and graphically displays the object according to its graphical attributes. When used with a processor, the FLS applies algorithms to non-responsive CPE units selected from the interactive map to identify possible common sources of a fault.
