Deleted Subdomain Still Serving Old Content (Persistent Cloudflare Cache)

What is the name of the domain?

cloudforzap.com

What is the issue you’re encountering

I deleted the subdomain chat.cloudforzap.com and also removed the server it was pointing to over 3 days ago. I also deleted the DNS records for this subdomain. However, the page from the old server is still being displayed when I visit chat.cloudforzap.com, even though it should no longer exist. It seems Cloudflare is still serving a cached version from the edge.

What steps have you taken to resolve the issue?

Deleted the DNS records for chat.cloudforzap.com

Removed the original server

Cleared the Cloudflare cache using the “Purge Everything” option

Cleared browser and router cache

Confirmed via DNS checker tools that there’s no active DNS record or IP resolving for the subdomain

Tested on multiple devices and networks, including incognito mode

What feature, service or problem is this related to?

DNS not responding/updating

What are the steps to reproduce the issue?

Open a browser

Visit my site

The old page is still served, even though the DNS has been removed and there’s no active server

The subdomain chat is not resolving in the Cloudflare nameservers for your domain or publicly…

Make sure that the DNS record is not being found local to you in your resolver, a hosts file or similar.

Thank you for the support provided!

I’d like to inform you that the issue has been resolved. I found that the old content was still being loaded on a few specific devices (around four), even after initially clearing the browser cache.

The solution involved a more thorough cleanup process, including:

  • Flushing the local DNS cache (ipconfig /flushdns);
  • Deep cleaning of browser caches;
  • Restarting the affected devices and the router.

After these steps, the subdomain chat.cloudforzap.com started working correctly across all devices.

Thanks again for your assistance and guidance.
