DNS Propagation: Why Domain Changes Take Up to 72 Hours to Update Globally

Domain changes require 24-72 hours to propagate across the Internet's global network of servers. This waiting period, known as "propagation time," is necessary for DNS updates to take effect worldwide.

During propagation, your domain may work on some devices but not others. This is normal and happens because:

  1. DNS records are stored in directories on ICANN-managed servers
  2. Internet Service Providers (ISPs) keep cached copies of these records
  3. ISPs update their caches periodically to reflect new DNS changes
  4. All ISPs worldwide must update their caches before changes are fully visible

When you enter a URL in your browser:

  • Your computer looks up the domain's DNS records
  • These records direct the browser to the correct server
  • ISPs use cached records to speed up this process
  • Cached records are shared among thousands of users

If you're not seeing your domain changes:

  • You're likely viewing a cached version
  • Wait for the cache to update naturally
  • Changes will appear once propagation completes

To monitor propagation progress:

  • Use WhatsmyDNS.net to check domain status
  • Allow full 72 hours before concerning about issues
  • If problems persist after 72 hours, verify your DNS settings

This process is standard across the internet and cannot be expedited. The best approach is to be patient while the changes propagate through the global network.
