How can I fix DNS propagation delays after changing my nameservers?
Asked on Sep 01, 2025
Answer
DNS propagation delays occur when changes to your nameservers take time to update across the global DNS network. This delay is due to the time it takes for DNS caches to refresh with the new information.
Example Concept: DNS propagation is the period during which DNS servers worldwide update their cached information to reflect changes in domain nameservers. This process can take up to 48 hours, depending on the TTL (Time to Live) settings of the DNS records and the frequency at which DNS servers refresh their caches.
Additional Comment:
- Ensure the TTL value for your DNS records is set to a lower value (e.g., 300 seconds) before making changes to reduce propagation time.
- Use online DNS propagation checkers to monitor the status of your DNS changes across different regions.
- Clear your local DNS cache using commands like "ipconfig /flushdns" on Windows or "sudo dscacheutil -flushcache" on macOS.
- Contact your DNS hosting provider if propagation delays exceed 48 hours, as there may be an issue with the DNS configuration.
