Power and weather behind internet outages in Gaithersburg
Pepco customers averaged 65 minutes without power in 2024, across 0.59 interruptions each, against 118 minutes for Maryland 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 Gaithersburg power outages when both go out together.
Montgomery County logged 880 storm reports since 2015, most often thunderstorm wind, flood, and flash flood. Reports peak in July. Power outages were named in 1 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 68.7% of Gaithersburg homes, cable 97.7% and copper lines 0%. 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.
