Why retries can become dangerous
A retry feels helpful in isolation. Under stress, many retries arrive at once and compete with the original traffic.

See how retries can amplify overload and destabilize distributed systems.
Key Observations
What to Notice
Timeout amplification
Shorter timeouts fail faster. Each failure can create more work before the old work has drained.
Positive feedback loops
More load creates more waiting. More waiting creates more retries. The loop can accelerate suddenly.
Why systems collapse
Once the service is buried, recovery lags behind. Retry traffic keeps circling even after new traffic calms down.
