The post highlights that the severity of incidents is often determined by retries, automation, failover, hidden dependencies, and load amplification. It cites a Discord 2026 case: a routine config change instantly killed 17% of session processes, and the subsequent reconnection wave overwhelmed downstream systems, breaking voice/video. It serves as a sharp lesson in backpressure: recovery traffic can become the next incident.
