DNS Propagation: Why Domain Changes Take Up to 72 Hours

Domain propagation takes 24-72 hours to complete because DNS changes must replicate across countless servers worldwide. This process, known as "propagation time," is necessary for your domain to work consistently across the internet.

During propagation, your domain may work on some devices but not others. This is normal and requires patience.

How Domain Propagation Works:

When you visit a website, your computer queries DNS records from ICANN's servers to locate the correct web server. To improve speed and efficiency, Internet Service Providers (ISPs) maintain cached copies of DNS records instead of looking them up each time.

These ISP caches update automatically every few days. Your domain changes won't be visible everywhere until all ISPs have refreshed their cached records.

Key Points About DNS Propagation:

  • Cannot be expedited or controlled by any single provider
  • Affects all domain changes globally
  • May show inconsistent results during propagation
  • Usually completes within 72 hours

During the Wait:

  • Use Whatsmydns.net to monitor your domain's propagation progress
  • Be patient as servers worldwide update their records
  • Remember that partial functionality is normal during this period

If issues persist after 72 hours, contact your domain provider to verify your DNS settings are correct.
