Client-side network information
This page displays your client’s network connectivity and environment data entirely using client-side JavaScript in the browser. It’s intended as a quick, same-origin way to inspect how your connection is being portrayed by the network. This requires JavaScript!
The Page and Browser categories are read using the location and navigator objects, which contain information about the current page address (URL) and web browser (user agent), respectively. The Netinfo category pertains to the Network Information API (using navigator.connection) and may not be supported on web browsers such as Firefox, Safari or Internet Explorer (see Can I use…). The Cdn-cgi data uses the Cloudflare edge network (/cdn-cgi/trace) to provide information about your connection to this website, which is served behind Cloudflare’s proxy. Finally, Timings pertains to data collected using the Performance API, which measures the page load process.
