dobre-knihy.cz is on the survey sweep, which works its way across the whole catalog rather than returning to one name on a schedule. Putting dobre-knihy.cz under watch moves it to the fast lane, where DomainDrift re-checks it about every 5 minutes and signs each reading, so a change becomes a dated event within minutes instead of waiting for the sweep to come round.

Watch dobre-knihy.cz Watching a domain needs a DRM3 account. The reading above stays free and public either way.

What this reading means

A security layer answered instead of the site. That is a working defence doing its job, and we record it as its own state rather than as a failure.

It does NOT mean the site is down or misconfigured. It also does not mean we were treated as hostile - most rules of this kind refuse every non-browser client alike.

What produces this, in rough order of how often

A WAF or bot-management rule refuses non-browser user agents by default.
Automated traffic from datacenter networks is challenged as a matter of policy.

These are the known causes, not a diagnosis of this domain. We recorded that nothing answered; we did not measure why.

Every field above is part of the same signed observation as the records below. Blank means not observed, never "none".

SIGNED-OUT VIEW Provider names, posture and counts are shown. The record values - every DNS answer, each subdomain hostname, raw TXT, IPs, cert names and WHOIS - are the product. Sign in for the full signed record, or use the API with a key.

The proof

Signed at scan time. Check the math yourself. Every line above is part of one signed observation. Re-hash it and check the Ed25519 signature in your own browser; the only network request the check makes is for the published public keys.
