6 resilience patterns for WebSocket clients, extracted from real-world mobile network conditions.

Mobile WebSocket connections fail in ways that local development environments don't surface. P99 latency on 4G networks is 5-8 seconds. A 5-second health check timeout causes false positives on every slow network.

When to use: Implementing WebSocket client reconnection logic, building real-time features with persistent connections, mobile app WebSocket handling, any client that maintains long-lived server connections.
