Power and weather behind internet outages in San Bernardino
Southern California Edison (SCE) customers averaged 158 minutes without power in 2024, across 0.99 interruptions each, against 280 minutes for California 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 San Bernardino power outages when both go out together.
San Bernardino County logged 759 storm reports since 2015, most often flash flood, flood, and heavy rain. Reports peak in August. 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 54% of San Bernardino homes, cable 90.2% and copper lines 8.5%. 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.
