Power and weather behind internet outages in New Haven
United Illuminating (UI) customers averaged 122 minutes without power in 2024, across 0.79 interruptions each, against 154 minutes for Connecticut 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 New Haven power outages when both go out together.
Fiber reports reach 62.3% of New Haven homes, cable 99.3% and copper lines 20.2%. 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.
