Endpoint Latency Test

What this test measures

Enter a host or URL and our server sends three HEAD requests to it, timing each one from start to response. You get each sample, the average, and the fastest and slowest. A HEAD request asks for headers only, so the numbers reflect connection setup and server response time, not download speed.

Reading the result

The times are measured from our server, not from your computer, so they show how quickly the target answers a well-connected client. Big gaps between the three samples usually mean the target is slow to respond under load or sits behind a rate limiter. A request that fails entirely is shown as unreachable.

To judge a proxy, compare the same target with and without it from your own machine: the difference is what the proxy adds. Our guide to testing proxy speed walks through measuring latency and success rate properly.
