Power and weather behind internet outages in Honolulu
Hawaiian Electric customers averaged 234 minutes without power in 2024, across 1.89 interruptions each, against 321 minutes for Hawaii 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 Honolulu power outages when both go out together.
Honolulu County logged 358 storm reports since 2015, most often heavy rain, flash flood, and flood. Reports peak in March. Power outages were named in 12 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 63.3% of Honolulu homes, cable 93.2% and copper lines 62%. 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.
