Downdetector (downdetector.com, Ookla) is a user-reported outage aggregator, showing when users complain en masse about a service (Gmail, Cloudflare, Instagram). Not suitable for monitoring your own site — it depends on report volume. Alternatives for own-site monitoring: Enterno.io (active probes); for external service outage tracking: IstheServiceDown, OutageReport, Status Gator.

No. Downdetector waits for user complaints. A small site will never get its own Downdetector page. For own-site monitoring — you need active probes (Enterno.io).
Downdetector cloudflare page + Cloudflare status page cloudflarestatus.com. For auto-detection in your app — Enterno heartbeat on the upstream.
Pro dashboard has a "dependencies" block — track external APIs via their status pages.
<a href="/en/status-settings">Enterno status page</a> — public URL, your monitors, incidents, response times.
