Latency Check

How this works

Every number here is a real, live measurement made by your browser — nothing is simulated, cached, or filled in by our server.

Real requests, not fake data

For each node your browser sends an actual GET /api/health request and times it with performance.now(). If a value is shown, that request really happened from this page moments ago.

Distance is what the number means

It is your round-trip time to that node's region. The closer the region is to you, the lower the ping — Europe → Germany, South/East Asia → India or Thailand. A higher value means a longer network path, not a slow device.

Method

One warmup request (discarded), then 5 sequential samples per node. Median and min are shown, 3s timeout per request, max 2 nodes measured at once. Any HTTP response counts as reachable; a network error or timeout counts as unreachable.

Privacy

Requests use no-cors mode, so only timing is read — response status and body are never inspected. Your IP is never stored, logged, or sent to our servers, and nothing is measured server-side.
