Santa Rosa in California
Santa Rosa runs on Xfinity's cable network, which reaches 99.3% of its homes and businesses and is the only wired provider at 100/20 Mbps for 57.1% of them. Fiber comes mainly from AT&T and Sonic, whose networks mostly reach different locations: fiber of any kind reaches 35.5% of locations, two or more fiber companies only 11.0%1.
Xfinity at nearly every address, fiber at about a third
The FCC counts 53,834 homes and businesses in Santa Rosa, as of June 30, 2026 (file revision of November 10, 2026). Xfinity reports service at 99.3% of them, over cable almost everywhere, with downloads advertised up to 2 Gbps. AT&T reports 90.5%, but most of that is DSL over copper phone lines; it offers 100/20 Mbps at 32.8% of locations. Sonic, which reports only fiber here, is the third wired network, at 23.2%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 (Viasat, Starlink, HughesNet) report service at nearly every location and are left out of the table.
Each share is the part of the city's locations where the company tells the FCC it serves, or could connect a standard installation within ten business days. Those reports can be challenged on the FCC National Broadband Map, where one house or apartment can be looked up. Satellite is reported everywhere, yet only 11 location in Santa Rosa depends on it alone.
Two fiber footprints, little overlap
Fiber to the premises from any company reaches 35.5% of Santa Rosa's locations, a share that ranks tied for 45th lowest among the 343 US cities of 100,000 or more. AT&T reports fiber at 22.9% and Sonic at 23.2%, with advertised downloads up to 5 Gbps and 10 Gbps. Frontier adds 171 locations. Two or more fiber companies are reported at only 11.0%1 of locations, so most homes with fiber have one fiber company, and which one depends on the address. In Oakland and San Francisco, where the same two companies build, the overlap is wider.

Coverage has grown. Fiber was reported at 24.9% of locations in June 2022, 34.8%3 in December 2025 and 35.5% now. Sonic was already there: in June 2022 it filed under the name Sonic.net, so provider lists that compare names show it as new. Two or more fiber companies were already reported at 6.1% of locations then. Over the same four years DSL fell from 79.8%2 to 75.1%1 of locations; DSL is still reported more widely here than in most large cities.
Gigabit uploads spread faster than fiber
The FCC's gigabit tier requires 1 Gbps down and at least 100 Mbps up. In Santa Rosa it is advertised at 68.7% of locations, against 24.9%2 in June 2022; the gain of 8.6 percentage points in the last six months alone ranks tied for 35th highest among large cities. Fiber reaches only 35.5%, so a large part of that tier is advertised over Xfinity's cable lines, the only other wired network that covers the city. Symmetrical service of 100/100 Mbps, at 68.7%1, has the same reach.

|---|---|---|---|---|
| Fiber available | 24.9% | 34.8% | 35.5% | 10.6 pts |

| DSL available | 79.8% | 75.1% | 75.1% | −4.7 pts |
The fastest advertised download tells the same story: 2 Gbps or more at 67.6%1 of locations, against 18.3%2 in 2022. These are providers' advertised maximums, not measured speeds, and a cable plan with a 100 Mbps upload is still far from symmetrical at gigabit speeds.
One wired choice at most locations
Wired service of at least 100/20 Mbps is reported at 99.6% of locations. What varies is the number of companies offering it at the same address. One company, almost always Xfinity, offers it at 57.3% of locations, the 50th highest share among large cities; across California the figure is 43.2%. Two or more wired companies are reported at 42.3%1, up from 33.7%2 in 2022.
Other cities north and east of the bay differ widely. In Solano County, fiber is reported at 42.9% of locations in Vallejo but at 21.8% in Fairfield and 18.6% in Vacaville; Concord, in Contra Costa County, is at 37.0%1, close to Santa Rosa.

Carrier home internet reaches fewer locations than in most cities
Licensed fixed wireless, which includes 5G and LTE home internet from the mobile carriers, is reported at 84.5% of Santa Rosa's locations, a share that ranks tied for 24th lowest among large cities and below California's 88.1%1. In June 2022 it was reported at 95.5%2.
Verizon has the widest carrier footprint, 34,557 locations or 64.2% of the city, with downloads advertised up to 300 Mbps and 100/20 Mbps at 15.9%. T-Mobile reports 59.3% of locations, with 100/20 Mbps at 17.8%. Two smaller networks report fixed wireless in parts of the city: GeoLinks at 0.1% of locations and Kwikbit at 0.4%. Wired service at 100/20 Mbps is missing at 223 locations, and fixed wireless offers that speed at 531 of them.

More households rely on a cellular plan alone
The Census Bureau's American Community Survey counts households, not locations, and its figures are estimates. In 2025, 15.7% of Santa Rosa households had only a cellular data plan for home internet (margin ±2.7 percentage points), against 8.0% in 2019 (margin ±2.3 percentage points5); the two ranges do not overlap. Statewide the 2025 figure was 12.9%. Households with a cable, fiber or DSL subscription were 79.3% (margin ±3.1 percentage points), and those with no subscription 2.9% (margin ±1.1 percentage points4).

| Households subscribing to cable, fiber or DSL | 79.3% ±3.1 | 78.8% | – | tied 157th of 340 |

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.
