How Nodown defines reliable monitoring

Nodown uptime monitoring is defined as a multi-region check workflow: run the same monitor from independent regions, confirm a failure only when enough regions agree, then notify the right channel and update the status page. The figures on this page describe Nodown product limits and monitoring methodology, not third-party reviews or customer-count claims.

"HTTP response status codes indicate whether a specific HTTP request has been successfully completed." MDN Web Docs, HTTP response status codes →
HTTP HTTP monitors evaluate status codes and response behavior against RFC 9110 and MDN status-code guidance. DNS DNS checks track domain-name answers against RFC 1035 so unexpected record changes can be reviewed quickly. SSL SSL certificate alerts are informed by the CA/Browser Forum baseline requirements for publicly trusted TLS server certificates. WEBHOOKS Webhook alerting gives technical teams an integration surface for runbooks, incident workflows, and API-driven operations.
