DNS Propagation
The process of DNS changes spreading across all DNS servers worldwide.
DNS propagation is the time it takes for a DNS change (like updating your website's IP address) to be recognized by all DNS servers around the world. When you change a DNS record, it does not update everywhere instantly. DNS servers cache records for a period defined by the TTL (Time to Live), so some servers may still serve the old record until their cache expires. Full propagation can take anywhere from a few minutes to 48 hours, though most changes are visible within 1-4 hours.
