Locating an Internet Service Provider can be quite difficult. In several regions, there are only a handful of alternatives, and certain rural areas may have merely one option. Even with these limited selections, it’s advantageous to grasp how your ISP stacks up against others. Speed is a key factor for most users, prompting us to examine the fastest ISPs of 2025 through Ookla speed evaluations.

Ookla measures internet connection speed and quality, frequently releasing reports that rank the top ISPs in the U.S. (Note: Ookla and Mashable operate under the same parent company, Ziff Davis.) These rankings are derived from millions of speed assessments, with some ISPs undergoing tests more than 25 million times in the U.S. alone.

The most recent speed test report, which also looked at mobile service providers, assessed ISPs based on speed, reliability, and availability. T-Mobile excelled in the mobile carrier rankings, whereas AT&T Fiber emerged as the leader among ISPs, making a notable impact in the sector.

Be aware that some local ISPs, like Wide Open West or Windstream, are absent from the newest Ookla report. Nevertheless, you can still perform your own speed tests to evaluate your provider against the top national providers.
