Claude AI is Currently Down: What We Know and How to Check Its Status

If you're trying to access Claude.ai right now and getting errors, login failures, or "service unavailable" messages — you're not alone.

Anthropic's Claude AI has been experiencing intermittent outages and elevated error rates recently, including today (April 28, 2026). Users have reported issues with Claude.ai, the web interface, Claude Code, and in some cases the API or authentication.

What We Know So Far

• Anthropic has acknowledged incidents involving elevated errors on Claude.ai and the API, along with periods where the service becomes unavailable.

• Today's issues appear connected to access problems and authentication errors, consistent with several recent disruptions in April 2026.

• These outages have affected chat functionality, logins, and related tools like Claude Code. While some components recover quickly, others can take longer to fully stabilize.

• Claude has seen strong demand growth, and Anthropic has noted that high traffic sometimes contributes to these stability challenges.

Outages like this aren't entirely new — similar problems popped up multiple times this month, often resolving within a few hours after Anthropic's team intervenes.

How to Check Claude's Current Status (Quick Guide)

Don't just refresh Claude.ai endlessly. Use these reliable sources instead:

1. Official Claude Status Page (Best Option) Visit: https://status.claude.com/ This is Anthropic's own real-time status dashboard. It shows the exact health of Claude.ai, API, Claude Code, Console, and other components, plus live incident updates.

2. Downdetector Check: https://downdetector.com/status/claude-ai/ Great for seeing user-reported spikes in real time and which features (chat, app, Claude Code) are most affected.

3. Anthropic's Announcements Keep an eye on their official channels or the status page for updates like "Investigating," "Identified," or "Resolved."

What You Can Do While Waiting

• Try a different browser or incognito mode (sometimes cache/login issues play a role).

• Wait 15–30 minutes and check the status page again — many incidents resolve relatively quickly.

• If you're a heavy user, consider having a backup AI option ready for critical work.
