Nameservers and DNS delegation
The NS records at your registrar tell the internet which DNS servers are authoritative for your zone. Wrong NS values cause email and website failures even if your zone file is perfect.
After changing DNS providers, allow time for registrar and resolver caches to update. Lower TTLs before a migration can shorten the transition window.
