Domain-name lookups use Cloudflare's public DNS-over-HTTPS resolver (1.1.1.1). The checker and the board run on Cloudflare Workers; the city named in each result is Cloudflare's data-center code for where the check ran.

The checker's certificate handling was tested against the test hosts at badssl.com (expired, self-signed, wrong-host and untrusted-root certificates), a project of the Chrome security team, and against a packet-dropping test host for timeouts.

The browser error messages quoted in the guides are Chrome's, Firefox's and Safari's own wording, read in October 2026.

There are no photographs on this site. The bakery in the examples is made up.
