DNS Update Delay: Propagation Issues

TODO: collapasable, copyable, download, etc

I created a Route53 hosted zone. I puyt the 4 nameservers into my domain registrat. I created an A record pointing to my ELB. It has been 5 minutes. Why don't the domain name resolve?DNS changes, including updates to records in Amazon Route 53 or changes to nameserver records at your domain registrar, can sometimes take longer to propagate due to DNS caching and the time-to-live (TTL) settings of the DNS records. Here are a few reasons why your domain name might not resolve immediately after making these changes:

1. DNS Propagation Time: Even though you've updated the nameservers at your registrar and added an A record in Route 53 pointing to your Elastic Load Balancer (ELB), DNS changes can take up to 48 hours to propagate globally. This is because DNS servers around the world cache records for a period of time specified by the TTL of the records.

2. TTL Settings: If the previous DNS records (including the nameservers) had a high TTL, DNS servers might still be serving the cached (old) records. New changes won't be visible until the cache expires.

3. Nameserver Update Delay: After updating the nameservers at your domain registrar, there might be a delay in those changes being recognized across the internet. This is partly due to the registrar's processing time and the propagation delay.

4. Configuration Errors: Double-check the nameserver records provided by Route 53 against those you entered at your registrar. Even a small typo can cause issues. Also, ensure that the A record in your hosted zone correctly points to the ELB's DNS name.

5. Caching on Your Local Machine or Network: Sometimes, your local DNS cache or your ISP's DNS cache may still hold onto old records. You can try clearing your local DNS cache or use a public DNS service like Google DNS (8.8.8.8 and 8.8.4.4) to check if the issue persists.

6. ELB Configuration: Ensure that your ELB is properly configured and operational. If the ELB is not correctly set up or is not in the "active" state, the DNS resolution might seem to fail when, in fact, the issue is with the ELB itself.

To diagnose the problem further, you can use tools like nslookup or dig to query your domain's DNS records directly from different locations or using different DNS servers. This can help you understand whether the issue is with DNS propagation, a configuration error, or something else.

If the problem persists beyond 48 hours, it might be worth double-checking all configurations, both in the Route 53 console and with your domain registrar. If everything seems correct, consider reaching out to AWS Support or your domain registrar's support team for further assistance.
