DNS Zone Restoration Assistance

Question

Hi,

I recently accidentally deleted my Lightsail instance, its static IP, and its DNS zone. Now I am trying to restore it by recreating these resources. However, when I create a DNS zone in Lightsail to resolve to my old domain, www.mydomain.com, the website does not load in my browser. Upon further investigation using https://www.whatsmydns.net/, I found that the DNS propagation checker still resolves to the old Lightsail instance, which has been deleted.

Do you have any suggestions on how I can resolve this issue?

Thanks,
Lisa

Make sure that you complete this step ([Step 4: Change the name servers at your domain’s current DNS hosting provider](https://docs.aws.amazon.com/lightsail/latest/userguide/lightsail-how-to-create-dns-entry.html#lightail-change-the-name-servers)) after creating the new Lightsail DNS Zone.  The name servers for the new (recreated) DNS Zone will almost certainly be different than the previous ones.

Once that is complete, you may have to wait for TTLs to time out in caching DNS servers accross the internet before they will do lookups to get the new address.  How long this will take depends on what the TTLs were set at in your old DNS Zone.

In the mean time, you can test DNS lookups against one of the name servers listed using the dig command in Linux/Mac OS.

`dig @  +short`

Hope this helps...
