Connection Lab
Measure server-route speed, HTTP latency and jitter, and inspect your request
Connects only to this tool server after you click. Uploads random synthetic data, never files or form content.
Small fixed-route test: 2 MiB download and 1 MiB upload per run.
This entry uses unencrypted HTTP. Only synthetic test data is transferred. Do not send passwords or private information.

Request seen by the server
Understanding the results
Each test uses about 3 MiB plus protocol overhead. Stop aborts the requests. Concurrency, request-rate and total-traffic limits apply.
Speed is a short HTTP transfer from your browser to this server, including server, proxy and network limits, not your broadband plan peak. Latency is the median of five round trips; jitter is the average absolute difference between adjacent samples.
Returns IP, server time and four non-sensitive headers only. Cookies, Authorization, Referer and query content are not echoed. The backend HTTP version may describe the proxy-to-service connection.
