Fan-Out Amplification Broadcast Multiplication, Subscriber Amplification	concept	WebSockets & Realtime	The property that one input event becomes as many output events as there are subscribers, making the workload proportional to audience size rather than to event rate - and the reason broadcast paths cannot sha…
Reconnect Storm Thundering Herd on Reconnect, Connection Stampede, Recovery Amplification	concept	WebSockets & Realtime	The synchronised burst of clients re-establishing connections after a disruption, which is far more expensive than steady-state traffic and routinely turns a brief network fault into a prolonged self-sustainin…
