Why Do DNS Server Errors Happen?

[Datarecovee]

Failing of DNS Server: This may occur due to:
1. Wrong DNS entries or wrong set up of A, CNAME, NS, or any other records.
2. Delaying propagation TTL values.
3. Cache poisoning, DDoS or domain hijacking.
4. Network issues or resolver issues.
In case these problems arise, you will receive a DNS_Error, rather than status quo resolution.
