Power and weather behind internet outages in Sioux Falls
Xcel Energy customers averaged 100 minutes without power in 2024, across 0.88 interruptions each, against 85 minutes for South Dakota 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 Sioux Falls power outages when both go out together.
Minnehaha County logged 445 storm reports since 2015, most often thunderstorm wind, flood, and hail. Reports peak in May. 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 64.3% of Sioux Falls homes, cable 80.7% and copper lines 73%. 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.
