Impact on Dev Workflows
If you rely on Claude for code generation, debugging, or AI-assisted development via the API, expect timeouts or 5xx errors. Consider falling back to local models or alternate services until resolution is confirmed. API clients should implement exponential backoff to avoid rate-limit penalties once service resumes.
This appears to be a global incident — no specific region or endpoint has been singled out yet. No ETA for fix has been provided.
