How Does the Speed Test Work?
Our speed test connects directly to Cloudflare's global edge network — the same infrastructure that powers millions of websites. This means your test data travels to the nearest Cloudflare data center, giving you the most accurate measurement of your real-world internet performance.
Download speed
Measures how fast data arrives at your device, affecting streaming, browsing, and file downloads.
Upload speed
Measures how fast your device sends data, important for video calls, cloud backups, and sharing files.
Ping & jitter
Ping (latency) measures the time it takes for a signal to travel to the server and back — lower means a more responsive connection, crucial for gaming and real-time applications. Jitter measures the variation in ping over time; lower jitter means a more stable connection.
