The Chaos Arena
A small live system. Real faults. Watch what actually happens instead of guessing from a multiple-choice list.
Pick a Scenario
The Retry Storm
Target: DB Primary. You'll inject added latency into the primary database. The API layer retries failed or slow downstream calls without backoff — watch what that does under sustained latency.
The Cache Stampede
Target: Cache. You'll crash the cache layer outright. 80% of normal traffic is a cache hit today — think about where that traffic has to go instead.
The Silent Fallback
Target: Payment. You'll inject a burst of payment failures. This system has an automatic fallback that queues failed payments for async retry instead of surfacing them as HTTP errors — decide what you're actually going to watch.
