When was cpf.org built?

Analyzed 3 November 2026. Re-analyze

Estimated launch

November 1998

Medium confidenceLikely range: May–November 1998

There's good evidence for the year, but the exact month is less certain.

BuiltWhen verified that cpf.org launched in November 1998 (71% confidence), despite the domain being registered in March 1996, resolving a 2-year domain parking gap where the domain was held before web content was deployed.
