System Design Failure Lab & Incident SimulatorAn interactive outage simulator for practicing production debugging.
A browser-based training lab that simulates high-traffic server outages. Engineers diagnose traffic spikes, configure rate limiters, and inspect logs under simulated stress.
Most software developers only learn how to debug production outages when something is actually burning in production at 3 AM.
Built an interactive outage sandbox with simulated traffic graphs, error logs, and mitigation buttons (like rate limiting, cache warming, and replica scaling) to practice incident triage.
Realistic incident scenarios including database lockups, traffic surges, and cache misses
Interactive controls to adjust rate limiters, add server replicas, and warm caches
Simulated telemetry showing latency, CPU usage, error rate, and queue sizes
Post-incident breakdown scoring how quickly you stabilized the system
