I removed a site from my old account and added it in the new. On the old and new account a site had/has only one “A” record but with different IPs. The strange thing is that new nameservers are different but they resolve IP of a removed site (and accordingly “A” record) from an old account.
Why the old “A” record is still alive and why the new doesn’t apply?
P.S. My domain’s authoritative DNS server use correct nameservers.
