Connection trace (/cdn-cgi/trace)
Open /cdn-cgi/trace on any site using the CDN to see your IP, the edge location serving you, and the protocol in use.
Open https://your-domain/cdn-cgi/trace in a browser or with curl. The edge node answers directly, the request never reaches your origin, and it isn't billed.
