I have issue with Cloudflare Registar. NS servers are lost for some DNS providers, including Cloudflare (184.108.40.206). If I understand correctly, I even can’t change NS servers in case of Cloudflare Registar.
Dig and whois details:
$whois nikanorov.mobi | grep 'Name Server'
Name Server: memphis.ns.cloudflare.com
Name Server: paislee.ns.cloudflare.com

When you transferred your Domain to Cloudflare you did not disable DNSSEC as required, and the parent zone contains DS records.
I’ll escalate this post for the attention of the Customer Support Team so they can get back to you here. If you have already contacted Support, please share your ticket number here so that they can track it.
I do see DS records. But I am not sure why does the domain still thrown SERVFAIL errors. Have you already raised a ticket for this one? If not can you please create a ticket and post the number so that we can escalate further as required?
Should I purchase a plan with support contract to resolve this issue faster? Root A/AAAA records for this domain are not critical, but some subdomains are. For example, some subdomains affect thousands of customers.
Thanks for this. I have update from the Registrar team that there is nothing wrong with the configs. Can I ask you to please toggle your DNSSEC once? If this does not resolve I will reach out to other team.
I understand this is frustrating but this is something very odd and hence we are trying to understand where is the problem
