<p><font face="Calibri">1) Consult the list of accredited domain
registrars on the IANA website
(<a class="moz-txt-link-freetext" href="https://www.icann.org/en/accredited-registrars">https://www.icann.org/en/accredited-registrars</a>), thus finding
confirmation of one particular registrar's website the CA was
looking for.<br>
2) Access the website found in point 1 above and query the
information available on a certain domain.<br>
3) At this point, sometimes (rarely) obtain, among other
information, also the email address of a domain contact.<br>

<p><font face="Calibri">Note that here I'm not talking about the
WHOIS protocol nor WHOIS servers, but about the information that
the domain registrar has the duty to collect and store (not
necessarily publish) about the subject who registered a domain.<br>

CAs were not consulting the right WHOIS server, despite a database of
correct WHOIS servers existing (at least for gTLDs). How would the problem
be better when it comes to finding the "right" website?
The gTLD registry agreement requires gTLD operators to update the IANA
Rootzone Database when their WHOIS server changes; I don't see a
similar requirement for keeping a database of website URLs up-to-date.
