什么是 BlockedOrDown？
BlockedOrDown runs a three-signal architecture across Cloudflare's global edge — edge probe, browser-side test, and MIME trap — to tell you exactly why a site isn't loading: global outage, ISP block, or local network issue. 5,000+ services covered. Zero accounts. Zero tracking. Zero stored data. Every check runs at the edge and disappears. You're completely anonymous — by design, not by policy. Built by a solo dev. No ads, no surveillance.
