I used to have a repo for a static web site years ago. Directed custom domain to it, all worked fine.

Tried removing the CNAME file from my new repo. The site got published under its
Restored the CNAME file — the error is back, and the naked Custom domain displays 404 again.
Please advice, who can I contact to ask to remove the “stuck” cname record from GitHub internals. Or maybe I should create a new repo with the same name as the initial one that was deleted?
