Why DNS Updates Can Take Up to 48 Hours to Propagate

Domain propagation is the process of updating DNS records across global internet servers. This typically takes 24-48 hours, though it can occasionally extend to 72 hours. During this time, your domain may work inconsistently across different devices and locations.

How Domain Propagation Works:

When you enter a URL, your computer checks ICANN's servers for DNS records to locate the correct website server. To improve speed, Internet Service Providers (ISPs) maintain cached copies of these DNS records instead of checking ICANN's servers every time.

These cached records update automatically every few days. Your domain changes won't be visible everywhere until all ISPs complete their cache refresh cycles. This is why:

  • Some users might see your site while others can't
  • Changes appear gradually across different locations
  • The process cannot be expedited

Monitoring Progress:

You can track your domain's propagation status worldwide using Whatsmydns.net. If issues persist after 48 hours, verify your DNS settings are configured correctly.

What to Expect:

  • Allow 24-48 hours for changes to take effect
  • Domain may work inconsistently during propagation
  • Different locations will update at different times
  • Process is automatic and cannot be sped up

Remember that propagation time is a standard part of how the internet works and affects all domain changes, regardless of your hosting provider or domain registrar.
