honest answersIs Anthropic down right now?
503Radar publishes a live Anthropic verdict at the top of this page, stamped in UTC and rewritten by the detection pipeline whenever the signals change — not a cached daily snapshot. We fuse crowd reports from public platforms with Anthropic's official status feed; when independent sources spike together we raise a signal, often before the official status page updates. A quiet radar means we have no evidence of an Anthropic outage — not a verified all-green.
How does 503Radar detect Anthropic outages?
We monitor public outage chatter across forums, social platforms and developer communities, first-party "seeing this too" reports from visitors, and the official Anthropic status page (status.anthropic.com). A statistical anomaly across two or more independent evidence classes becomes a Signal; an official acknowledgement upgrades it to Confirmed. The full pipeline is documented on our methodology page — no black boxes.
Why is Anthropic not working for me?
If 503Radar shows no elevated signals, the problem may be on your side: connectivity, DNS, a VPN or browser extension, or an account-specific issue. Try another network or device and check status.anthropic.com for maintenance notices. You can also file a report here — enough independent reports from different countries open a community watch on the board.
