What is DNS Propagation?

When you update a DNS record (like pointing your website to a new server or changing your MX records for Microsoft 365), the change doesn't happen instantly everywhere. It takes time for DNS resolvers across the world to clear their caches and fetch the new information. This process is called DNS propagation.

How long does it take?

Historically, DNS propagation could take up to 48 hours. Today, with modern DNS infrastructure (like Cloudflare, Azure DNS, or Route53) and lower TTL (Time To Live) settings, changes often propagate worldwide in minute - hough some stubborn local ISP resolvers may still take hours.

Why do records match in one country but fail in another?

This is the exact reason this tool exists. A user in Australia might be querying a local Telstra or Optus DNS server that still has the old record cached, while a user in the US querying Google (8.8.8.8) might see the new record instantly. Checking multiple global nodes gives you the true picture of your deployment.
