StatusCheck

Alerts

One confirmed failure. One alert.

An alert you learn to ignore is worse than no alert. Every notification StatusCheck sends has already been confirmed by a second region and carries the facts you need to act.

Alerts, in detail.

Alerts with the facts in them

Monitor, target, state change, failure reason, confirming regions, start time, and a link to the incident. Recovery alerts include how long it lasted.

No storms

One confirmed failure sends one alert per channel. Flapping inside a short window is grouped into the same incident instead of re-paging everyone who already knows.

Signed webhooks

Every webhook is signed with HMAC-SHA256 using a per-channel secret and retried with backoff. Events for down, degraded, up, incidents, and expiring certificates.

No per-responder fee

Route a channel to whoever should get it. Alert-only members are free and don’t take a seat, so nobody gets left off the alert to save money.
