My account was blocked, but the DNS never came back

@bonino97 Do you use Netlify DNS?

If so you may need to configure your DNS again yourself.

See:

I think under situations where Netlify “take down sites” they clear the DNS records and then don’t automatically restore them if it’s reverted for whatever reason.

I believe there can also be records that either their support add back for you, or you “recreate the site” so they get generated again.
