TTL for missing records

DNS & Network 1.1.1.1
#1

Is there any TTL for missing records in @1.1.1.1?

I use route53 as DNS for my domain.

I dig for missing record
dig @1.1.1.1 TXT 0zxc/com
dig @8.8.8.8 TXT 0zxc/com
and got no result, which was correct. After it, I added this record in route53.
I dig for this record once more time and 1.1.1.1 didn’t return this record. I had to wait about 15 minutes before it was in 1.1.1.1

Probably best to have a read of RFC 2308 and see if the behaviour described matches your experience.
