Recommended Resiliency Patterns
Circuit Breaker Pattern: Automatically trip and fallback to cache when cdnjs error rates exceed 15% in a 30s rolling window.
Idempotent Background Retries: Push failed API events into an asynchronous dead-letter queue with exponential backoff and jitter.
Multi-Region Edge Synthetic Consensus: Rely on SteadyStack to alert your team before end-users notice degradation.
