Impairment discovery using automatic geographical clustering
Systems and methods can provide for improved impairment discovery for broadband communication systems. In some implementations, such systems and methods can provide cluster outage detection and/or time-stamped outage data and visualization. Improved outage discovery can help operators plan repair and thereby reduce truck rolls and decrease network down-time.
