Hi Vercel Support Team,

I am having trouble adding my custom domain "sarita.ia.bo" to my project.

The domain validation logic is misidentifying "sarita.ia.bo" as a subdomain of "ia.bo", rather than recognizing "sarita.ia.bo" as an apex/root domain (eTLD+1).

Please note that "ia.bo" is already officially listed on the Public Suffix List (PSL) as an effective TLD under the Bolivian ccTLD (.bo / nic.bo). Because "ia.bo" is a public suffix, "sarita.ia.bo" is an independent registered apex domain.

It seems Vercel's internal copy or cache of the Public Suffix List is outdated and does not yet reflect this entry, causing the custom domain parser to fail.

Details:

• Domain to add: sarita.ia.bo
• Expected Apex/Root: sarita.ia.bo
• Public Suffix / eTLD: ia.bo (registered under NIC Bolivia / nic.bo)

Could you please update/sync your Public Suffix List cache or manually whitelist "sarita.ia.bo" as a root domain for my project?

Thank you for your help.
