Hi @dpsic,
Thanks for reaching out and welcome to Netlify’s Support Forums!
I see that your site was deleted, however the DNS Zone for dpsitcouncil.com is still there. You’ll need to go here and delete the DNS Zone.
If you’re unable to delete the DNS Zone, we can remove it for you, however we’ll need to verify that you control the domain. You can follow this Support Guide to create a TXT Record in order for us to verify. Once you’ve created the TXT Record, please let us know. Thanks!
