A client website has their domain name registered at GoDaddy. This domain points to Wix.com's nameservers. I've lowered the TTL in wix to 1 hour.
However, when we go live we'll be switching the nameservers themselves (with Godaddy).
When a zone record expires for the old site (wix), does the DNS look at wix directly for an update, or will it check back with the registrar (godaddy)?
In my mind the cached A-record would expire, but nothing is telling the DNS that the nameserver has changed. The nameserver is on a higher level. I'm not sure if that is correct, though? Or maybe when the cached record expires, it checks for a new record from the registrar. That's what is confusing.
So my question is:
Is changing the TTL of a specific zone record enough to make the nameservers themselves update sooner for visitors?
