What this check can tell you
This checks a few public requests at one moment. It does not test login, transactions, full page rendering or continuous availability. Browser errors do not always reveal whether DNS, certificates, routing or browser restrictions caused the problem. Results help investigate; they do not assign fault.
This page uses the same domain as the website. Save an offline copy in advance if you need a basic check when the domain is unreachable.
The independent check contacts Cloudflare. Like any website request, the destination can see your connection IP. This page does not store it in the report.
