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."
HTTP monitors evaluate status codes and response behavior against RFC 9110 and MDN status-code guidance.
DNS checks track domain-name answers against RFC 1035 so unexpected record changes can be reviewed quickly.
SSL certificate alerts are informed by the CA/Browser Forum baseline requirements for publicly trusted TLS server certificates.
Webhook alerting gives technical teams an integration surface for runbooks, incident workflows, and API-driven operations. See Nodown API and webhook availability.
