How we measure this: checks run from EU servers only, so a result here reflects what the EU sees, not a global view. A regional outage, CDN edge-cache issue, or bot/WAF protection that treats our monitoring probe differently than a real visitor can all cause this to disagree with Principle's own status page — that's a limitation of any third-party checker, not just this one.
