Claude Fable 5 API endpoint experiencing elevated error rates. Status page shows 'Investigating' phase—HTTP status code distribution, affected regions, user tier segmentation (free/paid/enterprise), and root cause (capacity/deployment/downstream resources) remain undisclosed. SDK/API client implementations should verify retry logic with exponential backoff, enable Request ID logging, and consider temporary timeout adjustments. Hold critical requests until impact scope is confirmed, or provision fallback routing. Monitor status.claude.com for real-time updates.
