DNS propagation is the time Domain Name System servers worldwide take to update and propagate information about a domain name. It occurs when changes are made to the DNS information associated with a domain name, such as an IP address change or new DNS records being added. During Domain Name System propagation, different DNS servers can have different versions of the DNS information cached. This is why a website may appear inaccessible or show the wrong content sometimes. Domain Name System propagation typically takes between 24 to 48 hours to complete, depending on the number of DNS servers involved. Read more about the purpose of DNS propagation and what affects it?
