Power and weather behind internet outages in Naperville
Naperville Electric Utility customers averaged 25 minutes without power in 2024, across 0.5 interruptions each, against 157 minutes for Illinois 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 Naperville power outages when both go out together.
DuPage County logged 417 storm reports since 2015, most often thunderstorm wind, hail, and flood. Reports peak in July. Power outages were named in 4 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 7.4% of Naperville homes, cable 99.5% and copper lines 82%. Cable is the main wired technology here. One neighborhood node feeds many homes, so a node fault usually shows up as a whole street offline at once.
