Reconnection Storm (2D): Exponential Backoff & Jitter

A mobile app's backend connection can drop for dozens of reasons — a cell-tower handover, a background app-server deploy, a load balancer hiccup — and when it does, every client that was connected notices within moments of each other and tries to reconnect at once. This top-down 2D simulator drops hundreds of mobile clients off a backend simultaneously and re-runs the reconnection storm under three real retry policies: no jitter (pure exponential backoff, lock-step and self-synchronizing), full jitter (delay drawn uniformly from zero to the exponential cap), and decorrelated jitter (each delay derived from the previous one). A capacity-limited server processes a fixed number of requests per tick; watch the load meter to see which policy drains the herd fastest without ever pinning the server at 100%.
