Claude's 500 API error

Thousands of users reported intermittent API Error 500 (Internal Server Error) across claude.ai, the web interface, Claude Code, and related services. Anthropic shared an update on its server status page.

“We are seeing increased errors on Claude.ai, API, and Claude Code,” the first message read. It was followed with: “The issue has been identified and a fix is being implemented.”

How to fix or work around API 500 errors

Here are the most effective troubleshooting steps while Anthropic works on the backend:

Check the official status page

Visit status.claude.com first. If it shows “All Systems Operational” but you’re still getting 500 errors, the issue may be regional or intermittent.

Basic refresh and retry

Refresh the page or restart your chat session.

Wait 30–60 seconds between attempts (exponential backoff helps avoid rate limits).

Try incognito/private browsing mode.

Clear cache and restart

Clear browser cache/cookies or app cache/data on mobile.

Force-close and relaunch the app or browser.

Restart your device and router.

Switch Networks / Disable VPN

Toggle between Wi-Fi and mobile data.

Disable any VPN or proxy, as they can interfere with Anthropic’s routing.

Use alternatives or fallbacks

Switch temporarily to another model/provider (eg GPT-4o or Gemini) via multi-model tools or wrappers.

Use old sessions or cached conversations if available.

Anthropic has not provided a specific ETA for full resolution today. Based on previous incidents, most major outages have been resolved within 2–10 hours once identified.

Yahoo outage

Meanwhile, Yahoo experienced a brief outage on Wednesday. Users said they were unable to access the mail, AOL services. Downdetector showed at least 2000 reports at one point. However, the numbers have come down.
