When .tr domain names migrated to the Trabis system, a general configuration about DNS updates was provided. DNS updates take place within certain rules These rules are as follows.

DNS server changes of the domain name take place every hour between 09.00 and 21.00, once at 01.00 and once at 06.00. In addition to this rule, changes made in the first half hour are transferred to the beginning of the next hour, while changes made after half an hour are updated one and a half hours later.
For example:

09:20 update --> 10:00
15:40 update --> 17:00
20:45 update --> 01:00
02:00 update --> 06:00

This is realized as follows.

In addition, we would like to remind you that after the update is provided, it will enter the propagation phase, and this process can be completed within 24-48 hours within the rules specified by ICANN.
