Thousand Oaks in California
Thousand Oaks had its fiber before the FCC began mapping: 83.1%2 of its homes and businesses were reported with fiber in June 2022, and 83.0%1 are now. What changed since then is everything around the two main wires. DSL nearly vanished from the filings, AT&T arrived with fixed wireless, and the part of the city where Spectrum is the only fast wired option has stayed about the same size.
Who reports service in Thousand Oaks
As of June 30, 2026 (FCC revision of November 10, 2026), the FCC map counts 38,781 homes and businesses inside Thousand Oaks, and two wired companies serve nearly all of them. Spectrum reports 97.2%, over cable with downloads advertised up to 1 Gbps, and fiber at 0.2%. Frontier reports fiber at 82.2% of locations, with downloads advertised up to 7 Gbps1.
| Spectrum | Fiber Cable | 97.2% | 97.2% | 1 Gbps | 14.4% |
|---|---|---|---|---|---|
| Frontier | Fiber | 82.2% | 82.0% | 7 Gbps | 0.1% |

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.
The other names on the list are mostly wireless. T-Mobile, AT&T and Verizon report fixed wireless home internet, and AT&T also reports small areas of DSL and fiber. GeoLinks, TPx Communications and EarthLink Business each report a few dozen locations or fewer. The order reflects how many locations each company reports, not service quality or price. A location counts as served when the provider says it could install service there within ten business days, and every listing can be challenged on the FCC map.
Two wires at most addresses, one at the rest
Wired service of at least 100/20 Mbps is reported at 97.3% of locations. At 82.8% there are exactly two wired providers at that speed, Spectrum and Frontier, a share that is 36th highest among large cities. Three or more are reported at 0.0%, against 6.5%1 across California: no third wired network reaches a meaningful part of the city.
The rest of Thousand Oaks has one wire. At 5,634 locations, 14.5% of the city, a single wired provider offers 100/20 Mbps, and Spectrum is the only one at 14.4%1. Mostly these are locations Frontier's fiber does not reach. Their share was 14.6%2 in June 2022, so the fiber map has not grown into them.
Source: FCC, National Broadband Map, data as of June 30, 2026. Different wired providers (fiber, cable or DSL; FCC provider IDs) reporting 100 Mbps down and 20 Mbps up or more at the same location. Fixed wireless and satellite are not counted.

| Area | None | One | Two | Three or more |
|---|---|---|---|---|
| Thousand Oaks | 2.7% | 14.5% | 82.8% | 0.0% |
| Simi Valley | 0.1% | 0.9% | 10.0% | 89.1% |
| California | 6.9% | 43.2% | 43.4% | 6.5% |
| United States | 7.8% | 36.6% | 44.6% | 11.1% |
The gaps are small. 1,050 locations have no wired provider at 100/20 Mbps, 245 reach that speed only through fixed wireless, and 18 have no land-based service at all, only satellite. Small as it is, that satellite-only share, 0.1%, is tied for 24th highest1 among large cities.
Fiber that was already built
Fiber coverage in Thousand Oaks barely moved after the first FCC map. The share of locations with fiber went from 83.1%2 in June 2022 to 83.0% in June 2026, a gain of 0.1 percentage points that ranks 14th lowest among the 343 cities of 100,000 or more. With fiber already at most locations in 2022, the room for growth was small. The city's 83.0% sits well above California's 47.8% and Ventura County's 62.7%1.
Its neighbors took other paths. Simi Valley went from fiber at 3.1%2 of locations in 2022 to 99.9% now; Oxnard is at 61.0%, and Ventura at 23.8%. Across the county line, Santa Clarita is at 18.3%1.

DSL nearly left the map
The largest change since 2022 is in copper telephone lines. DSL was reported at 41.4%2 of Thousand Oaks locations in June 2022 and at 2.8% in June 2026, a drop of 38.6 percentage points. California's DSL share fell by 15.3 percentage points1 over the same period. Frontier, the company with fiber across most of the city, now reports DSL at only a handful of locations, and most of what remains is AT&T's. The FCC map records what each company files, not whether copper lines were removed or simply dropped from its filings.

| Two or more fiber networks | 0.0% | 0.0% | 0.0% | 0.0 pts |
More wireless carriers, smaller reported reach
Licensed fixed wireless, which includes 5G home internet, was reported at 97.5% of locations in June 2022, 91.1%3 in December 2025 and 84.5% now, tied for 24th lowest among large cities and below California's 88.1%. The number of companies reporting it rose from 32 to 41 over the same years.
The new name is AT&T. In June 2022 it reported only a small number of locations in Thousand Oaks; it now reports 12,968, mostly over fixed wireless, but offers 100/20 Mbps at only 2.1% of locations. T-Mobile reports the widest wireless service, at 78.2%, with 100/20 Mbps at 26.5%. Verizon reports 11.9% and 100/20 Mbps at 6.4%1.
The speed of wireless offers has swung between releases. Licensed fixed wireless at 100/20 Mbps or more was reported at 7.3%2 of locations in 2022, 46.7%3 in December 2025 and 29.9% in June 2026, against 56.1%1 statewide. Carriers decide eligibility one address at a time, because everyone connected to a tower sector shares its capacity.
Upload speeds slipped in the latest release
Fiber is what gives Thousand Oaks fast uploads. Gigabit service with uploads of at least 100 Mbps, the FCC's 1,000/100 tier, is advertised at 82.8% of locations, against 67.4% statewide, and symmetrical 100/100 Mbps at 82.8%. Both shares were higher in December 2025, at 86.2% and 85.6%, while the fiber share held steady (83.2%3 then, 83.0% now). The six-month change in the gigabit tier, −3.4 percentage points, is tied for 27th lowest1 among large cities.
| Measure | Thousand Oaks | California | United States | Rank among largest cities |
|---|---|---|---|---|
| 1 Gbps download | 97.3% | 92.7% | 91.0% | 235th of 343 |
| Gigabit (1,000/100) | 82.8% | 67.4% | 72.3% | 225th of 343 |
| Wired 100/100 Mbps | 82.8% | 65.5% | 73.7% | 230th of 343 |
| 2 Gbps or more | 82.6% | 62.5% | 61.0% | – |

Downloads are a different picture: a 1 Gbps download is advertised at 97.3% of locations, and the fastest advertised download is 2 Gbps or more at 82.6%. At 14.7%1 of locations the fastest advertised download is about 1 Gbps, the top of Spectrum's cable tiers. All of these are maximum speeds that providers advertise, not measurements of what a connection delivers.
What households subscribe to
The Census Bureau's 2025 American Community Survey found 96.0% of Thousand Oaks households with a broadband subscription of any kind (margin of error ±1.9 percentage points), up from 90.9% (±2.8 percentage points5) in 2019; the two ranges do not overlap. Cable, fiber or DSL was the subscription at 81.3% (±4.2 percentage points), and 9.9% relied on a cellular data plan alone. Households reporting a satellite subscription came to 8.4% (±2.4 percentage points), 31st highest4 among large cities by point estimate, in a city where satellite is the only option at almost no location.
| Measure | Thousand Oaks | California | United States | Rank among largest cities |
|---|---|---|---|---|
| Households with a broadband subscription of any type | 96.0% ±1.9 | 95.6% | – | tied 102nd of 340 |
| Households subscribing to cable, fiber or DSL | 81.3% ±4.2 | 78.8% | – | tied 113th of 340 |
| Households relying only on a cellular data plan | 9.9% ±3.0 | 12.9% | – | 276th of 340 |
| Households with satellite internet | 8.4% ±2.4 | 7.8% | – | 31st of 340 |
| Households without an internet subscription | 3.9% ±1.9 | 4.4% | – | tied 237th of 340 |
Source: Census Bureau, American Community Survey 2025 1-year detailed tables. Rank 1 is the highest value. Period: 2025.
The survey counts households over a year and the FCC counts locations on one date, so the two sets of figures are compared only loosely. The California page maps Ventura County and every other county in the state, and Frontier's page shows where else it reports fiber.

Checking one address in Thousand Oaks
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.
