Abstract
Methods and systems to detect power outage are provided herein. The system includes a Cable Modem Termination System (CMTS) to periodically poll cable modems and determine cable modems of the plurality of cable modems that are offline based on the poll. The system correlates and aggregates locations of the cable modems that are offline to determine a geographic area where a percentage of the cable modems that are offline is higher than a predetermined threshold. A report is generated indicating a power outage in the geographic area when the percentage is above the predetermined threshold.
