How long does it take for DNS records to change?

How to make DNS changes with minimal downtime?
First reduce the TTL of the record that you want to change to a minimal value, e.g. 30 seconds. Then wait “old TTL value” seconds. So we’d have had to wait 1 hour in our last example after reducing the TTL to 30 because the old TTL was 1 hour. After that period you can change your data. Or you can now even further reduce the TTL to 5 seconds.
How does time to live work in DNS?
Every DNS record has a Time to Live ( TTL) value, which is the time DNS servers should store that record in cache. Even if a record is changed, DNS servers will continue working with its formal value from cache until this time has passed.
