Degraded functionality for Claude Cowork on Windows
Sep 10, 2026 · Resolved Sep 14, 2026
This issue has been resolved. Microsoft has released a September 14 Windows update that fixes it: https://support.microsoft.com/en-us/servicing/os/windows-11/2026/09/kb5129195-windows-11-24h2-25h2-security-update
A Windows update released September 8 has left Claude Cowork on Windows unable to run local commands, because its workspace can no longer reach your computer's drive. For most users, chat and file reading and editing still work. There's no in-app workaround yet, and restarting or reinstalling won't help. Microsoft has developed a fix and is working to release it.

Frequently Asked Questions
Is Claude down right now?
Check the status indicator at the top of this page. It pulls directly from Anthropic's official status page. If Anthropic is experiencing any issues, you'll see it reflected here. This real-time monitoring helps teams quickly identify whether performance problems are caused by Anthropic infrastructure or their own systems.
What does this Anthropic status page track?
This page tracks Claude, Claude API, Claude Code, Claude Sonnet, and Claude Opus using data from Anthropic's official status page. You can see current component health, active incidents, and a history of past issues. This visibility is crucial for teams building resilient AI applications that need to route around provider outages.
How often is Anthropic status updated here?
We check Anthropic's status page every 60 seconds to ensure you get near real-time status updates. How quickly issues show up here depends on how fast Anthropic updates their own official status. For production systems that need instant failover, Bifrost can automatically detect and route around degraded providers.
Why monitor Anthropic status?
Anthropic outages often matter most to engineering, agent, and internal tooling use cases where Claude is deeply embedded into day-to-day developer workflows. Real-time status monitoring enables proactive incident response and helps teams decide when to route traffic to alternative providers for maximum uptime.
What should I do when Claude or Anthropic has an outage?
When Anthropic experiences an outage, the best practice is automatic failover to alternative AI providers. Bifrost is an open-source AI gateway that automatically detects Anthropic degradation and routes LLM traffic to healthy alternatives like OpenAI (GPT-4), Google Gemini, Cohere, keeping your application running with zero manual intervention. This intelligent routing ensures your users never experience downtime from a single provider's issues.
How can I prevent Anthropic downtime from affecting my application?
Production AI applications should never depend on a single provider. Bifrost AI Gateway provides automatic multi-provider failover, intelligent load balancing, and health-based routing. When Anthropic degrades, Bifrost instantly routes requests to operational alternatives while maintaining API compatibility. This architecture approach is used by teams running mission-critical AI features.
What are common causes of Anthropic outages and degraded performance?
Based on incident history, Anthropic issues most frequently affect claude.ai, Claude Code, and Claude Cowork. Common causes include infrastructure scaling issues, regional cloud provider problems, API gateway overload, and deployment errors. Teams using Bifrost can configure automatic routing rules based on component-level status to minimize impact.
