DNS propagation is the process by which updated DNS records spread across all DNS servers globally after a change is made. When you update nameservers, add a DNS record, or make other changes, it can take 24 to 48 hours for all DNS servers worldwide to reflect the update. During propagation, some users may see the old version of your site while others see the new one. TTL (Time to Live) values affect propagation speed.
FAQ
How long does DNS propagation take?
DNS propagation typically takes 24-48 hours, though some changes can propagate in minutes. The speed depends on TTL values, ISP caching, and geographic location.
