Is 1.1.1.1 down right now? Live check from Cloudflare's edge: HTTP status, response time, final URL after redirects, server header and whether the TLS certificate is valid, with an up/down verdict. Call it when a user or agent says "1.1.1.1 isn't loading" to tell a real outage from a local problem. $0.01 per check.
