I just recently removed the configuration to point the domain to the site as I am urgently trying to get the site live again. I have tried creating a new account and deleting the old one which is why I imagine the site gives the suspended message. When I try and add my custom domain to the new site on the new account, I am getting that:
Another site is already using this domain, Domains must be unique across Netlify. Currently another site is using this domain. If you don’t know which site, please contact support for guidance.
Do you know why this would be the case? @coelmay
