DNS Propagation: Why Domain Changes Take Up to 72 Hours
Domain propagation is the process of updating DNS records across global internet servers. This process typically takes 24 to 72 hours to complete and cannot be expedited.
When connecting a custom domain to your website, DNS records must be distributed to servers worldwide. During this period, known as "propagation time," your domain may work inconsistently across different devices and locations.
How DNS Propagation Works:
Internet Service Providers (ISPs) maintain cached copies of DNS records to speed up website loading times. When you make changes to your domain's DNS settings:
- Your updates are registered with ICANN's directory servers
- ISPs gradually update their cached DNS records
- Different locations may see the changes at different times
- Complete propagation occurs when all ISPs update their cache
Why It Takes Time:
- Global server distribution
- ISP cache update schedules
- Different update frequencies across providers
- Geographic location variations
During Propagation:
- Your domain may work intermittently
- Some users might see the old settings while others see new ones
- Changes will gradually become visible worldwide
- Progress can be checked using WhatsmyDNS.net
Best practice is to wait the full 72 hours before troubleshooting any domain connection issues. If problems persist after this period, verify your DNS settings are correctly configured.
Remember that this waiting period is a normal part of how the internet works and affects all domain changes globally, regardless of the service provider.
