This probably changed the set of assigned name servers. Do check they are still the same and never keep name servers for Cloudflare after deleting a zone.
If they are glen.ns.cloudflare.com and serena.ns.cloudflare.com, are you sure you have a plan configured in the Cloudflare dashboard? I have seen a few issues like that…
The parent registry (e.g. .mx’s name servers) responds NXDOMAIN for linkmas.mx, indicating that the domain does not exist in the DNS system.
A domain WHOIS does unfortunately not reveal any state.
However, the pattern is very consistent with a domain name that may have been suspended from the domain registry.
I would therefore suggest you to contact your domain registrar, asking them for an explanation on why the domain name isn’t being published in the DNS, so that they can troubleshoot and/or eventually escalate things up the chain towards the MX registry.
