irozhlas.cz has an AboutUs profile for public website intelligence, ownership context, trust signals, monitoring, and owner verification.
AboutUs has not vetted this site. Everything below is what we could measure automatically. Anything you do on the site — paying, sharing personal details, downloading — is between you and the site, not AboutUs.
Current facts
Latest available measurements; dated entries retain their dates. These are measurements, not an endorsement of the site.

Domain registered Sep 8, 2010 — 16 years old.
latest result
Registrar on record: INTERNET CZ, a.s. — unchanged since AboutUs began tracking (Nov 7, 2026).
Authority 55/100— ahead of 55% of the August 2026 scored sampleClear
Why this authority score
55 is a percentile: higher than 55% of sites we score.
How it's calculated
Prominence (Tranco rank #34,097)+7
Verified continuity: 16.2 years (RDAP registration)+10
Security & email hygiene+3
Calibration adjustment (published map)+9
Model score: 29/99 — what these reason lines add up to.
Published Authority (percentile): 55/100 — this site's rank against the August 2026 scored sample. Public Authority is capped at 99.
Safety evidence
No unexpired threat-feed result; name-similarity check available (recorded about 47 days ago); 3/3 transport and email checks available (oldest recorded about 47 days ago). This is evidence coverage, not a probability that a website is safe.
No caution flags in the available scoring observations; this is not a complete safety assessment
