How to use
- Press start. A small request is sent to our server at the selected interval and the round-trip time is drawn on the graph.
- Leave it running for a minute or two. Red lines on the graph are lost requests.
- Start a download or a video on another device to see how much the latency rises under load (bufferbloat).
- Use "Measure regions" to find the nearest cloud data centers; many online games run their servers there.
Frequently asked questions
What are good values for gaming?
Ping under 40 ms, jitter under 5 ms and no packet loss are excellent. Up to 80 ms ping and 10 ms jitter is fine for most games. Packet loss above 1 % causes rubber-banding and lag spikes.
Why is this ping higher than in the command line?
Browsers cannot send ICMP or UDP packets, so the test uses short HTTPS requests. These add a few milliseconds of processing. Use the values to compare over time rather than against a game's own ping display.
Can I ping a specific game server?
Not directly from a browser. The region table measures the cloud data centers where many game servers are hosted, which is a good estimate for the nearest server.
