Backup internet options in Denver
Xfinity (99% of homes) and CenturyLink / Quantum Fiber (95%) each report service to more than half of Denver homes. At an address that can get both, they run on separate lines.
Home 5G and fixed-wireless plans from T-Mobile Home Internet (80%) and Verizon (78%) report coverage of Denver homes (Verizon’s figure combines Fios fiber and 5G Home). They run over cell towers rather than cable or fiber, so they can work when a wired network is down. Cell coverage by area is 100% for 4G LTE and 97% for 5G.
About 8.2% of Denver households, roughly 27,500 homes, get online only through a cell plan. For them a mobile outage is an internet outage.
Power and weather behind internet outages in Denver
Xcel Energy customers averaged 352 minutes without power in 2024, across 1.68 interruptions each, against 255 minutes for Colorado 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 Denver power outages when both go out together.
Denver County logged 218 storm reports since 2015, most often hail, thunderstorm wind, and flash flood. Reports peak in June. Power outages were named in 21 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 Denver homes, cable 93.3% and copper lines 49.2%. 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.
