What is Domain Propagation?
Propagation ExplainedUpdating the nameservers of a domain usually takes 24-48 hours to take effect. This period is called Domain or DNS Propagation. It is the time period that the root nameservers and cache records across the globe update your website's DNS information. During propagation, not all of your website's visitors are directed to the new nameservers; some visitors will still be directed to the old nameservers until propagation is complete.
The length of time when visitors are directed to the new nameservers depends on their physical location, ISP, and some luck; it is something that is beyond our control. Once propagation is complete, your website will appear, and your email will be fully functional.
How to check if DNS propagation has completed?
There is no definitive way to tell when propagation is complete. However, you may use online DNS checkers in order to track if the DNS record information has already propagated.
DNS Checker provides a free DNS lookup service for checking domain DNS records against a randomly selected list of DNS servers in different corners of the world. This is where you may confirm whether a website is completely propagated worldwide or not.
