What we watch on every website check
Every request captures the signals ops teams actually care about.
Response time + status code
p50/p95 latency, HTTP status, response size. Alert on slow-but-technically-up degradation, not just outright failure.
Content assertions
Substring match, regex, or negative match. Detect when the login form disappears, checkout button is missing, or your site starts returning a maintenance page.
SSL certificate expiry
Free bundled watchdog — 30 / 14 / 7 / 1 day alerts before expiration. Chain validation catches misconfigured intermediates.
Distributed checkers
15+ regions. Dual-location confirm before firing so a single flaky vantage point never wakes you up.
Redirect + header tracing
Follow chains, capture each hop's status. See exactly which redirect is broken, not just "it failed".
Malware + blacklist scan
DNSBL + safe-browsing checks so you find out you're listed before Google search does.

We check, confirm from a second region, then alert. No 3 AM wake-ups for one-off flakes.
Alerts anywhere your team lives
Route per monitor, per severity — production pages the on-call rota, marketing sites drop into a Slack channel.
