What you can investigate

Compare status, certificates and content across the published IPv4 and IPv6 endpoints. Review the affected endpoint or page, the measurement time and the suggested next action before changing your site.

Scope and privacy

Inputs and results are encrypted in our database and tied to this browser’s private ownership cookie. Only public destinations are allowed. Reports last up to 24 hours within the shared 500-report history; private recovery backups have a separate lifetime.

Results describe the listed endpoints and this measurement time. DNS and certificate preflights are bounded observations; they do not certify worldwide availability, reproduce every certificate-authority decision or independently validate the complete DNSSEC trust chain.
