Hello all,
I have a specific situation, and since I'm not that quite experienced with DNS servers I would really appreciate your help.
Domain test_domain.com have public nameservers ns1.test_domain.com and ns2.test_domain.com.
Both of these servers have different A records, as you can see from the image.
Now, the configuration of the network is like this :
1. When Primary link is up, backup link is down, and so only DNS Server 1 is visible from the Internet.
2. When Backup link is up, primary link is down, and so only DNS Server 2 is visible from the Internet.
Assuming that TTL of the A records are 60s, the question is, when primary link goes down, and backup link goes up, how long before DNS Server 2 records are visible from the Internet?
Thanks.
