Internet providers measured in Colorado, ranked by speed
Median real-world speeds for the 5 fixed home internet providers with at least 100 distinct connections in Colorado, fastest first. These are the speeds their customers measured, not advertised plan speeds, and not a statement of who can be bought at a given address.
| # | Provider | Download | Upload | Latency | Connections |
|---|---|---|---|---|---|
| 1 | Bluepeak | 229.3 | 89.3 | 41 ms | 100+ |
| 2 | Comcast | 211.0 | 45.5 | 20 ms | 2.5k+ |
| 3 | CenturyLink | 178.4 | 132.6 | 12 ms | 1k+ |
| 4 | Spectrum | 119.5 | 26.1 | 29 ms | 250+ |
| 5 | Starlink | 34.1 | 14.0 | 31 ms | 250+ |
Starlink is a satellite service: a single browser stream over a link with a long round trip measures well below the figures satellite operators quote, and the latency column shows why.
Measured in Colorado and named rather than ranked: AT&T, T-Mobile US, Verizon. In Colorado each of these is the operator's mobile network rather than a wired home line, and a browser test cannot tell a phone from a 5G home gateway on the same network. Ranking them beside fibre and cable would compare two different products.
Also measured, with too few connections for a median we would stand behind: BAM Broadband, Fort Collins Connexion, Ting.
Internet in Colorado: what the data shows
In Colorado, the median real-world download speed is 130.7 Mbps, 10% below the median published state of 145.6 Mbps, ranking #32 of the 39 states and districts with enough data to publish.
Colorado shares the second-lowest latency we publish, 24 ms, with Connecticut.
Uploads median 44.0 Mbps and latency 24 ms. That is among the lowest latency we publish, so live video and gaming should feel responsive on a typical connection.
Desktop and mobile tests run at about the same median speed, with mobile making up 27% of tests.
Across the 5 fixed providers with enough connections to rank here, medians run from 229.3 Mbps (Bluepeak) down to 34.1 Mbps (Starlink), a 6.7× spread inside one state. Which network reaches an address matters more here than which state the address is in.
The Colorado sample carries enough tests to name 11 providers, 15 counties and 22 cities and localities. Denver was its most-used test server, taking 85% of the tests among the five busiest.
Figures are medians of 10k+ browser-based tests from 5k+ distinct connections, first half of 2026. Each connection counts at most three times, third-party sources are capped, and datacenter networks are excluded, so one busy line cannot move a state. That makes these numbers a different series from the national figure on the United States page, and they are not directly comparable to it.

Frequently asked questions
What is the average internet speed in Colorado?
The median real-world download speed in Colorado is 130.7 Mbps, with 44.0 Mbps upload and 24 ms latency, measured from 10k+ browser-based speed tests on SpeedOf.Me.
Where does Colorado rank among US states?
Colorado ranks #32 of the 39 states and districts we publish, 10% below the median published state. We publish a state only where at least 2,000 distinct connections back the number, so 12 of the 51 are not listed at all.
Why is this lower than the speed my provider advertises?
An advertised speed is the maximum the line can carry. This is a real-world measurement through a browser to neutral servers on the open internet, which is what a video call, a download or a game actually gets. Wi-Fi, the device and time of day all sit between the two.
Which internet provider is fastest in Colorado?
Of the fixed home internet providers with at least 100 distinct connections in Colorado, Bluepeak has the highest median real-world download speed at 229.3 Mbps, ahead of Comcast at 211.0 Mbps. That is the median its customers measured here, not an advertised plan speed, and a provider is only as fast as the line that reaches your address.
Which internet providers were measured in Colorado?
11 providers had enough tests in Colorado to name: AT&T, BAM Broadband, Bluepeak, CenturyLink, Comcast, Fort Collins Connexion, Spectrum, Starlink, T-Mobile US, Ting, Verizon. 5 of them carry a ranked median speed on this page: the rest are either a carrier's mobile network in Colorado rather than a wired home line, or below the 100 distinct connections we require before publishing a median. That list is not a market-share estimate or a statement of who can be bought at a given address.
Are speeds on phones lower than on computers in Colorado?
Tests run on phones and tablets, over home Wi-Fi or a cellular connection, are 27% of the Colorado sample and median 131.2 Mbps. Tests run on desktops and laptops, which are almost always on a fixed line's Wi-Fi, median 131.2 Mbps. This is a device comparison, not a comparison of providers.
