Ping Test
Latency is the round-trip time of a request; jitter is its variation. These are web requests, not ICMP packets, so values can differ from the ping command.

How this test works
Probe: HTTP GET to the /cdn-cgi/trace path of the nearest Cloudflare node, answered by the node itself. Count: 10 sequential probes in Quick and Minimal mode, 20 in Full mode. Timing: Resource Timing responseStart minus requestStart when the browser exposes it, otherwise wall time. The timing source is recorded with the result.
How to read the result
Latency: median of successful probes. Min: lowest successful probe. Jitter: mean absolute difference of consecutive samples, in measurement order. Failed probes are counted in a separate field and excluded from the statistics. A rate limit response (HTTP 429) stops the run and is flagged.
What is typical
The scenario estimates on the internet speed test page use latency limits of 40 ms and 75 ms for games, and 100 ms and 300 ms for calls. Their jitter limits are 20 ms and 100 ms for games, and 30 ms and 100 ms for calls.
