Centennial in Colorado
In Centennial the most widespread fiber network belongs to neither the cable company nor the old phone company. Ting reports fiber at 84.2% of the city's homes and businesses, over lines that start on a backbone the city built itself, and Xfinity's network reaches 99.9%. Only 10.8%1 of locations are left with a single wired provider at 100/20 Mbps.
The wired networks and who files them
As of June 30, 2026, the FCC's National Broadband Map lists 35,028 homes and businesses inside Centennial's 2020 city limits. Xfinity reports service at 99.9% of them, Ting reports fiber at 84.2%, and AT&T reports fiber at 38.9%, with its fixed wireless service filling in much of the rest of its 66.2%. CenturyLink's copper lines, now listed only as DSL, reach 59.3%1.

Source: FCC, National Broadband Map, data as of June 30, 2026. Share of the area's broadband serviceable locations where the provider reports service as of June 30, 2026. "Only wired option" is the share of locations where it is the single wired provider at 100/20 Mbps. Provider-reported and challengeable; speeds are advertised maximums, not measured; no prices. Satellite providers (HughesNet, Starlink, Viasat) report service at nearly every location and are left out of the table.
"Reports service" means the provider tells the FCC it can install service there within ten business days; residents can challenge a listing they find wrong. The shares describe the city as a whole and are revised as filings change (this page uses the revision of November 10, 2026).
Ting's fiber starts on a city-built backbone
The largest fiber footprint in Centennial does not come from the incumbent phone company. The city finished building its own fiber backbone in 2018 and leases capacity on its central ring to Ting Fiber under a long-term agreement, according to the City of Centennial's FiberWorks page. Ting builds the lateral lines that reach residents itself. The city also leases fiber to other users, including Avata Networks and the Cherry Creek School District.
In the FCC data, Ting already reported fiber at most of the city in June 2022 and has added addresses since. It now offers up to 1 Gbps with matching uploads at 84.2% of locations, and almost all of them also have Xfinity: Ting is the only wired provider at 100/20 Mbps at 0.0%1 of locations.
A second fiber network on more than a third of the city
Fiber from any provider reached 77.5% of locations in June 2022 and 86.8% in June 2026. The larger change is overlap. In 2022, two or more separate fiber networks reached only 3.5%2 of locations; now 36.6% have them, the 46th highest1 share among the 343 cities of 100,000 or more.

The second network carries a different name depending on the year. In the FCC's location-level files, the phone company's fiber in Centennial was filed by CenturyLink in June 2022 and December 2025. In the June 2026 files a fiber footprint of about the same size as December's is filed by AT&T, which reported no Centennial service in 2022, and CenturyLink's records are DSL only. The Denver page shows the same change in the city next door. AT&T advertises up to 8 Gbps1 on that fiber.
Copper is shrinking at the same time. DSL was reported at 87.3%2 of locations in 2022 and at 59.3% now, and CenturyLink offers 100/20 Mbps over it at only 9.1%1 of locations.
Three wired choices are common, one is uncommon
Wired service of 100/20 Mbps or more reaches 99.9% of Centennial's locations, and only 381 have no wired provider at that speed. The question for most addresses is how many wires, not whether there is one.
| Measure | Centennial | Colorado | United States | Rank among largest cities |
|---|---|---|---|---|
| No wired choice | 0.1% | 10.6% | 7.8% | tied 319th of 343 |
| One wired choice | 10.8% | 32.4% | 36.6% | 247th of 343 |
| Two wired choices | 46.1% | 41.8% | 44.6% | 205th of 343 |
| Three or more wired choices | 43.0% | 15.2% | 11.1% | 52nd of 343 |
| Wired providers at 100/20 Mbps | 5 | 78 | 1,510 | tied 146th of 343 |
Source: FCC, National Broadband Map, data as of June 30, 2026. Rank 1 is the highest value. FCC file revision of November 10, 2026. Shares are of broadband serviceable locations (homes and businesses), not people.
43.0% of locations have three or more wired providers at 100/20 Mbps, up from 13.6%2 in June 2022, and 89.1% have at least two, against 57.0% across Colorado. Xfinity is the only fast wired option at 10.8% of locations, addresses where neither Ting nor AT&T reports fiber. On average a location has 2.321 wired providers at that speed.
Speeds: the top advertised tier moved to 2 Gbps
In June 2022 the fastest advertised download at 99.8%2 of locations was between 940 Mbps and 2 Gbps. By June 2026, 95.5% of locations had a provider advertising 2 Gbps or more, mostly Xfinity's cable network, which reports the same top speed in both directions in Centennial. Xfinity's own fiber, at 0.3% of locations, is advertised up to 2 Gbps1.

Upload speeds changed more than downloads. Gigabit service with uploads of 100 Mbps or more (the FCC's 1,000/100 tier) is advertised at 99.5% of locations, up 30.8 percentage points since June 2022, a share that ranks tied for 19th highest among large cities; across Colorado it is 79.4%. Symmetrical wired service of 100/100 Mbps reaches 99.3%1. All of these are maximum advertised speeds filed by providers, not measurements.
Fixed wireless from carriers and local operators
13 ground-based providers report service in Centennial, almost twice the wired count, because fixed wireless operators fill out the list. T-Mobile reports home internet at 92.1% of locations and Verizon at 62.0%; each offers 100/20 Mbps at a smaller share (37.7% and 18.0%). Local wireless networks cover parts of the city: AERUX Broadband at 21.3%, Kellin Communications at 13.7% and BAM Broadband at 11.7%1.
Wireless capacity is shared on each tower, so carriers limit sign-ups by address; a reported location is not a guaranteed opening. Only 24 locations reach 100/20 Mbps through fixed wireless alone, and satellite is the only option at 11 location.
Households: few depend on a phone plan
In the Census Bureau's 2025 American Community Survey, 89.3% of Centennial households subscribed to cable, fiber or DSL (margin of error ±1.5 percentage points), against 79.0% statewide. 6.4% relied only on a cellular data plan (margin ±2.2 percentage points), the 6th lowest share among large cities by point estimate, and 3.0%4 had no internet subscription. The survey counts households over a year, while the FCC counts locations on one date, so the two sets of figures are not directly comparable.

Checking one address in Centennial
The figures on this page describe the whole area. Which providers report service at a single home or apartment is shown only on the FCC's own map: search the address at broadbandmap.fcc.gov. If a provider is listed there but cannot actually connect you within ten business days, or the location is missing or misplaced, the map has a button to file a challenge; providers must respond, and corrections flow into later releases. Prices and plans are not part of the FCC data: each provider must show them on its broadband facts label at the point of sale.
