Our retry loop made an outage worse. The circuit breaker stopped the cascade.
A software engineer detailed how a retry loop exacerbated an outage with Anthropic's API, leading to significant wasted calls and extended recovery time. To prevent future incidents, they developed a Rust-based circuit breaker library called `llm-circuit-breaker`. This library implements a simple state machine to halt requests when an upstream service becomes degraded, protecting against cascading failures when combined with retry logic. AI
