Route 53 nameserver update stuck In Progress for 19 days.

I understand you're experiencing a prolonged delay with your Route 53 nameserver update. While I can provide general information about DNS propagation, I cannot directly access or escalate specific support cases, operation IDs, or account-specific issues.

Typically, when you change nameservers associated with a domain registration, DNS resolvers cache the names of nameservers, and it can take up to 2 days for changes to fully propagate across the internet. However, a 19-day delay is unusual and suggests there may be a specific issue with your domain registration or nameserver update process.

For your situation, I recommend:

1. If you have AWS Support on a Basic plan, consider upgrading to a paid support plan (Developer, Business, or Enterprise) to get direct technical support and faster response times for your case.

2. Try reaching out through the AWS Support Center directly to follow up on your existing case, or create a new support case if possible.

3. Verify that the nameservers you're trying to update to are correctly configured in your Route 53 hosted zone.

4. Check with your domain registrar to ensure there are no holds or locks on the domain that might be preventing the nameserver update.

Since this appears to be an account-specific technical issue that has exceeded normal propagation times, direct engagement with AWS Support is necessary to resolve it.
