Network Latency Test — Latency is the time a request takes to travel from your device to a server and back. This test sends a short series of tiny requests to several well-known public endpoints and reports the median, minimum, and jitter for each — side by side, so you can compare.
The test sends a handful of tiny anonymous requests to public endpoints and times the responses in your browser. No data about you is attached and nothing is stored.

What is network latency test?
Latency is the time a request takes to travel from your device to a server and back. This test sends a short series of tiny requests to several well-known public endpoints and reports the median, minimum, and jitter for each — side by side, so you can compare.
The comparison is the diagnostic. If every endpoint is fast but one is slow, the problem is that service or its route. If every endpoint is slow, the problem is local: your Wi-Fi, your ISP, or your device.
Each endpoint is pinged six times after one warm-up request (which absorbs connection setup), and the numbers shown come from the measured round trips only.
How to use it
-
Run the test
Endpoints are pinged one at a time; results appear as each completes.
-
Compare medians
A single slow endpoint points at that service; uniformly slow numbers point at your connection.
-
Watch jitter
High jitter (wide wobble between pings) hurts calls and gaming more than a slightly higher median.
Examples
Diagnosis example
Reading a typical result table.
Result: Cloudflare 12 ms, Google 18 ms, GitHub 45 ms, one endpoint 480 ms — your connection is fine; that one service or its route is the bottleneck.
