About FaultLine
A regional ISP that thinks every household and business deserves a network operator that actually cares about uptime.
Founded in Tucson, 2008.
FaultLine started with four engineers, a closet of refurbished gear, and a strong opinion that the existing duopoly was not trying hard enough. We started in Sam Hughes, climbed poles in the summer heat, and grew one neighborhood at a time.
Sixteen years later we serve 240,000+ customers across Tucson, parts of Phoenix, and a growing rural footprint in Cochise and Graham counties. We are still privately held, still headquartered downtown, and still pick equipment we would run ourselves.
If you have ever talked to a FaultLine support tech, you have talked to someone in Tucson. That is the part we are proudest of.

Honest pricing
The price you sign up for is the price you pay. No "regulatory fee" mystery, no auto-renewal price hike.
Local people
Our NOC is in Tucson. Our installers live in the neighborhoods they serve.
Build it well
We pick equipment we would run ourselves, and document everything we deploy.
Own the screw-up
We post-mortem every outage publicly and credit accounts without you asking.
