A change of name servers moves control of every DNS record to another provider. It is normal after a planned switch and a reason to look closer if nobody planned it.
You moved your DNS to a new provider, or your host changed its name servers as part of a migration. In both cases, someone on your side did it.
An old setup was restored, a registrar changed a default, or a person with account access made an edit. In rare cases, someone without permission gained access to the account.
Check who has access to the registrar account and whether any change was planned. The registrar's account history, where it exists, often shows what was changed.
Everything depends on the name servers. If they point to a place where your records do not exist, the website and email can stop working.
Domain Night Watch notices when the name servers of a domain change and alerts you. Open Domain Night Watch
