I still see non-Netlify nameservers

% dig shsparky.com NS
shsparky.com.		3600	IN	NS	ns1.phase8.net.
shsparky.com.		3600	IN	NS	dns3.p01.nsone.net.
shsparky.com.		3600	IN	NS	dns4.p01.nsone.net.
shsparky.com.		3600	IN	NS	dns1.p01.nsone.net.
shsparky.com.		3600	IN	NS	ns0.phase8.net.
shsparky.com.		3600	IN	NS	ns2.phase8.net.
shsparky.com.		3600	IN	NS	dns2.p01.nsone.net.

You’ll need to ensure *.phase8.net nameservers are removed.
