Have Any Questions?
Wondering how we measure speed and how accurate the results are? Get the facts behind the test.
The test measures three things: download speed (how fast data comes to you), upload speed (how fast you send data), and ping/latency (the delay in milliseconds). It does this by sending and receiving small packets of data between your device and our test servers.
A single test is a snapshot, not the full picture. Accuracy can be affected by other devices on your network, background apps, or temporary network congestion. For a true picture, run 3 tests at different times of day and take the median result.
Yes. For the most accurate measure of your ISP’s performance, choose the closest geographical server. Testing to a faraway server adds distance and hops, lowering speed and increasing ping—which reflects real-world experience for international sites.
No. A VPN will always slow your connection and route traffic through a distant server, masking your true ISP speed. For an accurate measurement of your raw internet speed, disable your VPN before testing.
