Abstract: Aspects of the present disclosure are directed toward power outage assessment using customer-site communication devices which are powered by utility power lines and which communicate with a remotely-situated computer server over a broadband network according to certain schedules. The server can receive from the devices, communications indicative of an operating status of each respective communication device as expected according to the schedules. In response to receiving and/or not receiving the respective communications from the devices and taking into account other parameters, the server can assess a possible power outage within one or more regions by comparing the received communications and threshold criteria associated with the schedules. Based on such criteria, the server can detect and report on conditions suggestive of a power outage in regions associated with the communication devices.
