Hi,
This morning we had DNS issues with microsoft azure DNS zone. It was working until yesterday. We are not able to access any DNS records from our local machines.
As a work around we added Azure DNS name servers to our local machines and it is able to resolve DNS records.
How can i fix this issue permanently?
Thanks,
-Sagar.

To address the persistent DNS issues encountered with Microsoft Azure DNS zone, here are steps that can be taken for a permanent resolution:
Validate DNS Configuration: Thoroughly inspect the DNS zone setup within Microsoft Azure to ensure accuracy. Pay close attention to DNS records, name servers, and any custom configurations. It is vital to verify that the appropriate DNS records are present and correctly configured.
Allow for DNS Propagation: It is essential to account for the time required for DNS changes to propagate throughout the internet. Confirm that ample time has passed since making any modifications to the DNS zone. While DNS propagation typically takes a few hours, it can occasionally take up to 48 hours for changes to fully propagate.
Review Network Settings: Conduct a comprehensive review of the network settings and confirm that the local machines are accurately configured to utilize the Azure DNS name servers. Verify that the DNS server settings on the local machines correctly point to the Azure DNS name servers.
Test DNS Resolution: Employ tools such as nslookup or dig to perform DNS lookups and verify the successful resolution of DNS records from the local machines. If the lookups fail or produce inaccurate results, it signifies a potential issue within the DNS configuration.
- Troubleshoot Connectivity: If the local machines cannot access DNS records, thoroughly investigate network connectivity with Azure. Ensure that no firewall rules or network restrictions are obstructing DNS traffic between the local network and Azure. Perform connectivity tests to ascertain accessibility to the Azure DNS name servers from the local machines.
By following these steps diligently, it is anticipated that the DNS issues can be permanently resolved, thereby re-establishing proper DNS functionality for the local machines utilizing the Microsoft Azure DNS zone.
