Is Anthropic down right now?

No. Our checks are finding no problems with Anthropic right now. That verdict is live, and the banner at the top of this page carries it too. We re-check Anthropic continuously using its official status feed, direct network probes and reports from visitors, stopping at the first check that gives a clear answer, and the page updates itself as soon as anything changes. A green verdict does not rule out a fault affecting only some users or regions.

The problems visitors report most often on this page are API errors, no response / timing out, website / app down, 5xx error pages, rate limited, can't log in and slow or laggy. Those are the options the report button offers for Anthropic, chosen for how this service actually fails rather than a generic list, and the "user reports" chart above breaks down which ones people are picking right now.

Our checks run from one place on the internet, so a fault limited to your region or network can be real while our probes succeed. With Anthropic specifically, Anthropic's API infrastructure, web chat servers, and authentication systems can fail independently, and regional routing or your API key permissions may cause failures while their main status page shows green. That is why this page reports what it observed rather than declaring the service healthy, and why reports from other visitors count toward the verdict.

For Anthropic, try sending a simple API request with curl to their API endpoint, or load claude.ai in an incognito window to rule out login cache issues. A problem that follows you across networks and devices is very unlikely to be yours.

If this page shows evidence of problems, the fault is most likely on Anthropic's side. Specifically: do not retry API calls in tight loops, as this burns through your rate limit and quota faster, making recovery slower once service returns. Reporting it here helps other people see they are not alone.

Continuously, around the clock. Anthropic publishes a machine-readable status feed, so our first check reads it directly and reports what Anthropic itself says. If that feed is unreachable we fall back to a direct HTTP probe, then an ICMP ping, then reports from visitors. The verification tier box on this page names whichever check produced the verdict you are reading, so you can see how direct the evidence is.

Yes, at status.anthropic.com, and it is linked further up this page. That is Anthropic's own account of their service and it is the place to look for their estimate of a fix. We read it where we can, but we publish our own observations beside it rather than only repeating theirs, because an operator's status page can lag a problem their users are already hitting.

No. status.buzz is an independent monitoring site operated by LuzLab LLC, with no connection to Anthropic or anthropic.com. It reads publicly available endpoints and status feeds, and publishes what it observed. For account or billing problems you need Anthropic's own support, not us.
