Claude API experiencing degraded performance for US Midwest traffic
Original: Degraded performance on the Claude API
Importance: 本番API障害として既存ユーザーに即影響し、アプリケーション可用性に直結するため
Summary
Anthropic's Claude API experienced degraded performance on September 10 affecting users whose traffic routes through the US Midwest. Users reported elevated latency and request timeouts. The incident was identified but no resolution timeline or root cause details were disclosed. Existing applications may face increased error rates, requiring stronger timeout handling and failover logic during the incident window.
Key Points
- Latency and timeout elevated for US Midwest-routed traffic
- Root cause identified but no resolution timeline or details disclosed
- Existing API calls require stronger error handling reinforcement
View developer notes (APIs, breaking changes, migration)
Claude API production endpoint (api.anthropic.com) experienced latency spike for US Midwest routed traffic, affecting standard request/response cycles and increasing timeout exception rates. No specific error codes, affected models (Claude 3.5 Sonnet/Opus), or region failover options were detailed in the status update. Developers should strengthen retry logic with exponential backoff, implement regional failover if available, and monitor error metrics (429/5xx rates) via usage APIs during incident resolution.
