Recursive Resolver - The DNS server your device communicates with is called the recursive resolver and is issued to you automatically by your ISP, but can be also configured on your router or individual devices. These DNS severs are ideally located in close geographical proximity to return results as fast as possible. These servers will cache a copy of the DNS results to speed up future DNS lookup requests.

Root Name Server - This type of DNS server is responsible for returning the IP address of the TLD (Top Level Domain) nameserver. For instance, if it is trying to resolve example.com, the root name server returns the IP of the TLD name server that runs .com domains.

TLD Name Server - This name server returns the authoritative name servers for each domain under the Top Level Domain it's responsible for. The .com TLD name server will return results for example.com but not example.org.

Authoritative Name Server - This stores DNS servers' configuration data for specific domain names.

I WILL GET DNS SERVERS AGAIN.  TLDNAME SERVER.   OR WHAT OTHER.

WHAT COMPANY YOU RECOMMEND..

Just checking, you are not creating new entries every time your server drops from the list, are you?  The entries remain registered for several months before they are actually deleted, and even if they do get deleted they can still be recovered unless the name gets used by a new server.

No, I just update the existing one.

I understand why these checks are in place, but for instance currently tests are failing on some servers because of this check:

dig A www.abs.gov.au @88.198.92.222 +short

• Recv: "65.8.56.73" "65.8.56.105" "65.8.56.90" "65.8.56.115"
• Expecting: "52.222.186.102" "52.222.186.98" "52.222.186.59" "52.222.186.119"

But that particular domain, seems to be very inconsistent right now

So that could potentially lead in many servers being removed.
