Winning Canary Battles but Losing the War

Problem:
Canaries reduce deployment risk, but they do not detect risks that emerge minutes or hours later—dependency overload, chain reactions, retry storms, or slow degradation.

Canaries Lie About Long-Term Safety

Why It Matters:
Most outages happen after a "successful" rollout. The canary was narrow; the system interactions were wide.

Impact:
Teams believe the deployment was safe while the system slowly drifts into failure.

Most outages happen after a 'successful' rollout. The canary was narrow; the system interactions were wide.

Insight:
Deployment checks are not enough. The system needs continuous validation of safety after rollout.
