Power and weather behind internet outages in Ann Arbor
DTE Energy customers averaged 483 minutes without power in 2024, across 1.25 interruptions each, against 470 minutes for Michigan 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 Ann Arbor power outages when both go out together.
Washtenaw County logged 166 storm reports since 2015, most often thunderstorm wind, hail, and flash flood. Reports peak in June. Power outages were named in 26 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 32.7% of Ann Arbor homes, cable 92% and copper lines 63.5%. 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.
