FAQ

Why might a technology be missing? The check reads the page as it is served — HTML, scripts, headers and cookies — without running it in a browser. Technologies that only appear after the page's JavaScript runs can be missed.

A site came back as BLOCKED. It turned the request away (HTTP 403 and the like), as some large sites do with any automated visit.
