Bind: Why doesn't it recognize newly created domain names?

Hello. There is a bind server. Yesterday I created a website (with my own DNS servers). After a couple of hours, Google's DNS (8.8.8.8) had already resolved the site's domain name, my DNS did not. Today still my DNS didn't recognize the site's domain name until I ran:

rndc flush
rndc reload

As I understand it, editing the negative cache TTL time (aka Minimum) will help me - but for which zone? I have a bunch of zones on my server, but I'm having trouble recognizing domain names that don't belong to my zones.

ttl is set for a zone in SOA or a specific DNS record and the maximum afair can be 7 days.
On your dns (bind) you can reduce the response caching time: max-cache-ttl seconds;
If the provider's servers or forwarders are used, then nothing can be done about it.
