Availability of .io names is checked against the registry's own RDAP server (rdap.identitydigital.services) and DNS-over-HTTPS. On this site your browser asks that server directly for a first, provisional answer; our server's check confirms it, and only that answer is cached. Premium suspects (such as very short names) and brand-protected labels also get a third signal, Fastly Domain Research, before they are shown as available.
