Speed Test
Measures your internet connection’s download speed and latency by downloading a test file from a CDN. Upload speed is not currently measured. Uses cloud-based processing.

Frequently Asked Questions
How is my privacy protected?
Nothing of yours is uploaded or stored. The test downloads sample files from a CDN to measure throughput — that test traffic is the measurement itself, and no personal data leaves your browser.
What exactly is measured?
Download speed and latency against CDN test files. Upload speed is not currently measured.
Why do results vary between runs?
Throughput depends on network congestion, Wi-Fi conditions, VPNs, and device load. Run twice and take the better reading for a fair number.
Does it measure upload speed too?
Not currently — it measures download speed and latency using a CDN test file.
What does the test actually download, and what if ping is blocked?
Latency pings the delay-zero probe endpoint with a 10-second ceiling, falling back to 45 ms estimated when blocked; speed downloads the roughly 1.2 MB CDN image at 1000 by 1000 with a 30-second abort (progress maps received bytes over 1200000 to the middle of the bar), and the display caps at 950 Mbps. Example: 1200000 bytes in 2 seconds computes to about 4.6 Mbps before the cap.
