Latest available measurements; dated entries retain their dates. These are measurements, not an endorsement of the site.

Domain registered Jul 1, 2003 — 23 years old.
latest result
Registrar on record: Corporation Service Company (Singapore) Pte Ltd — unchanged since AboutUs began tracking (Nov 15, 2026).
We withhold an authority number until independent evidence (global rank, link-graph presence) has accrued. The facts we do have about this site are shown below — we'd rather say “not enough signals yet” than invent a low score.
Safety evidence
No unexpired threat-feed result; name-similarity check available (recorded about 43 days ago); 3/3 transport and email checks available (oldest recorded about 43 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
