Canary9 watches continuously
Global synthetic checks run on your schedule from multiple regions. Every failure is recorded with timing, headers, and error context.
Know before your users do
When a check fails, you get a clear alert immediately, with enough context to act on: what broke, where, and how bad.
Alerts with context you can act on
Every alert from Canary9 includes the check region, HTTP status, response time, error body, and a direct link to the incident timeline. You open it knowing exactly what broke, where, and when.
- Region-specific failure isolation
- Full response body capture on failure
- Incident timeline with check-by-check history
- Alert deduplication: one incident, one alert thread
