We notice before you do.

A metric spikes, the alarm turns red, remediation does its job and everything returns to green. Most incidents are never seen by a customer, because they are resolved before they turn into an outage.

  1. HEALTHY Monitoring runs continuously, metrics stay under threshold.
  2. ALERT Load crosses the threshold, the alarm fires within seconds.
  3. AUTO-REMEDIATION Automation responds before anyone picks up a phone.
  4. HEALTHY The system returns to normal; the incident stays on record.

Resilience is shown, not promised.

Data lives in several zones at once. Losing a zone means rebuilding from its neighbour — no data lost, and no waiting for someone to reach a console.
