What is CenturyLink internet?
CenturyLink is a residential internet brand of Lumen Technologies, Inc., which kept its copper-based consumer services when it sold its consumer fiber-to-the-home business in eleven states to AT&T on February 2, 2026. That sale included Quantum Fiber, now sold as Quantum Fiber from AT&T. Centurylink.com, checked September 23, 2026, sells CenturyLink Fiber, with a tier up to 940 Mbps in limited areas, and Simply Unlimited Internet tiers up to 140M.
The same site says service is month to month with no annual contract or early termination fee, includes unlimited data with no overage charges, and comes with leased Wi-Fi equipment that must be returned, while fiber installation is free. Before the AT&T sale, Lumen's FCC filings as of December 31, 2025 showed meaningful coverage in 17 states, including Arizona, Colorado, Minnesota, Oregon, Utah, Washington and Wisconsin; that is FCC-reported coverage, not an address check.
In the same FCC data, Xfinity reports service in 968 and Spectrum in 581 of the 3,260 census places where Lumen does.
