DNS Propagation: Why Domain Changes Take Up To 72 Hours

Domain propagation is the process of updating domain changes across global internet servers. This process typically takes 24-72 hours to complete and cannot be expedited.

When connecting a custom domain, the waiting period (propagation time) is necessary for all DNS servers worldwide to recognize the changes. During this time, your domain may work inconsistently across different devices and locations.

How DNS Propagation Works:

DNS records function like an internet directory, telling browsers which server hosts your website. When you type a URL:

  1. Your computer queries DNS records from ICANN-maintained servers
  2. ISPs (Internet Service Providers) maintain cached copies of DNS records
  3. These cached records help load websites faster for large numbers of users
  4. ISPs update their cache every few days to detect DNS changes
  5. Your domain changes become visible only after all ISP caches update

Why It Takes Time:

  • ISPs worldwide must update their cached DNS records
  • Different ISPs update at different intervals
  • Geographic location affects update speed
  • Browser caches can also affect how quickly changes appear

Monitoring Progress:

You can check your domain's propagation status using Whatsmydns.net

If domain issues persist after 72 hours, verify your DNS settings are configured correctly. Common symptoms during propagation include:

  • Website working on some devices but not others
  • Inconsistent access across different locations
  • Temporary inability to access the site

Remember that this waiting period is normal and necessary for proper domain functionality across the global internet infrastructure.
