Methodology
We rated the largest internet providers in the U.S. for 2024. Each provider was rated on a scale of 1 to 5 based on over a dozen factors, including speed, cost, availability, fees, customer satisfaction, connection type and more. We also used data from the Federal Communications Commission (FCC) to compare the average speed offered by internet companies in the U.S. to set a baseline for what is considered a good internet speed. Additionally, we analyzed data from the American Customer Satisfaction Index (ACSI) to understand how each internet service provider (ISP) fares in customer service and perceived value.
How to choose a provider in Boulder, CO
Boulder’s diverse landscapes can impact internet service availability. Ensure your provider covers your specific area, especially if you live in remote parts of Boulder. Here are a few considerations when choosing the best internet provider for you.
- Internet usage: How you use the internet determines the best internet speed for you. If you have several connected devices for streaming, video calls and gaming, high-speed fiber is the best option. If you only have a few devices and don’t spend much time browsing the web, speeds up to 500 Mbps will do.
