Power and weather behind internet outages in Harrisburg
PPL Electric Utilities customers averaged 455 minutes without power in 2024, across 1.25 interruptions each, against 336 minutes for Pennsylvania as a whole. Cable nodes and fiber cabinets run on batteries that last hours, not days, so a long power cut can take internet down even for homes whose own power has returned. See Harrisburg power outages when both go out together.
Dauphin County logged 207 storm reports since 2015, most often thunderstorm wind, hail, and flash flood. Reports peak in June. Power outages were named in 4 of those storm episodes. Wind, ice and flooding damage poles and buried lines, which is how a storm turns into an internet outage as well as a power outage.
Fiber reports reach 80.1% of Harrisburg homes, cable 99.9% and copper lines 0.3%. Where fiber runs to the home, a red or blinking LOS light on the optical terminal points to a line problem that a restart will not fix.
