When Ookla was founded in 2006, high-speed home internet was just becoming available in many locations, and consumers needed a reliable way to test their network speed. Speedtest®, the company’s flagship product, is the most accurate tool for measuring a network’s capabilities. Today, modern connected experiences require reliable, consistently high performance across many additional metrics beyond download speed, including low latency for gaming, high-quality video streaming, good upload speeds for teleconferencing, and fast page load times while browsing on a mobile device.
In this evolving connectivity landscape, Ookla remains fiercely committed to measuring worldwide internet performance — as well as availability, quality of service (QoS), and quality of experience (QoE) of fixed broadband and mobile networks. For over 17 years, Ookla has been perfecting the way we test connectivity services and transparently reporting on their performance. By capturing real-world metrics and delivering insights back to network operators and policymakers, Ookla serves as the bridge between consumers and the telecommunications industry.
Every day, millions of people press the “Go” button on Speedtest to better understand the performance and quality of their internet connections. This consumer-initiated testing reflects how people actually experience the internet, when and where it actually matters to them. Because Ookla has the world’s largest network of testing servers located across every country and major population center, Speedtest does not introduce any extra travel time as the data passes between the device and server — which provides the most accurate measure of real-world network speed.
In addition to consumer-initiated testing, Ookla collects billions of mobile network samples daily, which measure radio signal levels, network coverage and availability, and QoE metrics for a number of connected experiences, such as streaming video, video conferencing, gaming, web browsing, and CDN and cloud provider performance.
