Backup internet options in Phoenix
Cox (89% of homes) and CenturyLink / Quantum Fiber (86%) each report service to more than half of Phoenix homes. At an address that can get both, they run on separate lines.
Home 5G and fixed-wireless plans from T-Mobile Home Internet (70%) and Verizon (54%) report coverage of Phoenix 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 98.9% for 5G.
About 11.6% of Phoenix households, roughly 70,800 homes, get online only through a cell plan. For them a mobile outage is an internet outage.
Power and weather behind internet outages in Phoenix
Arizona Public Service (APS) customers averaged 87 minutes without power in 2024, across 0.93 interruptions each, against 88 minutes for Arizona 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 Phoenix power outages when both go out together.
Maricopa County logged 1,448 storm reports since 2015, most often thunderstorm wind, flash flood, and hail. Reports peak in August. Power outages were named in 18 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 27.2% of Phoenix homes, cable 73.7% and copper lines 73.9%. Copper lines carry a large share of service here. DSL is sensitive to heavy rain and old wiring, and a blinking DSL light after a restart points to the line.
