When Claude API starts returning 429 under high load, most systems don’t just slow down—they collapse: queue buildup, retry storms, upstream timeout chains, and pager noise. ...
当 Claude API 在高并发下开始返回 429，很多系统不是“慢一点”，而是直接雪崩：队列堆积、重试风暴、上游超时、下游告警连锁。 ...
Running both Claude and OpenAI in production sounds resilient—until a slow failure hits: latency climbs, 429s spike, quality drifts, and everything still looks “up.” This guide gives you a practical dual-stack degradation runbook: timeout probing first, circuit-based cutover second, and an error-budget dashboard to keep business impact bounded. ...
你在生产里同时接 Claude 和 OpenAI，最怕的不是单点故障，而是慢故障：超时变多、429 变密、质量飘忽，系统还“看起来活着”。 这篇给一套可直接落地的双栈降级方案：先做超时探测，再做熔断切流，最后用错误预算看板兜住业务节奏。 ...
