Your site just broke — ask SiteTriage why. Give it a URL or domain and it runs live, read-only diagnostics from the edge: DNS resolution and propagation, the exact TLS certificate the server is presenting right now (including TLS 1.3), HTTP status and redirect chains, email authentication (SPF, DKIM, DMARC), and domain registration and expiry. It then returns the most likely root cause, ranked, with concrete fix steps — instead of guesses. Ideal for the deploy moment: apex-vs-www misconfigurations, stale DNS after a host migration, propagation lag, certificate errors, redirect loops, and emails landing in spam. Stateless and anonymous: no accounts, no stored data.
