How to read a regional check
- All 16 regions failing
- The hostname is failing from every probe location. That usually means the origin is down, the TLS certificate has expired, or authoritative DNS is not answering. It is not a problem on one network path.
- One region or continent failing
- When a single city or one continent is offline and the rest return HTTP 200, the origin is up. The failure is usually a CDN or anycast edge route, or a regional cloud impairment between that probe and the site.
- All 16 regions return 200, but it fails in your browser
- The site is reachable from our probes. A local failure is usually a stale ISP DNS cache, a corporate firewall or VPN, or a browser extension blocking the request.
- HTTP 403 or 429 from the probes
- A 403 or 429 from many cloud probes often means a WAF or Cloudflare bot challenge is blocking AWS IP ranges. That is not the same as an application outage. Compare the status code with what your browser receives.
