What means domain name propagation process and how this can impact your website or blog ?
A domain's DNS (Domain Name System) converts web URLs (such as www.madebyvasilis.site) into IP addresses (such as 126.96.36.199) used by computers to exchange data across the internet. In short, DNS matches names with numbers to deliver websites to your browser.
Whenever you change your domain's DNS, your domain host notifies the root DNS servers, which in turn notifies the ISPs (Internet Service Providers). This process is known as domain propagation.
Important: Domain propagation may take up to 48 hours to complete.
During the domain propagation process:
You may not be able to view your live site online.
Your previously connected live site may appear on your domain.
You may not receive emails connected to your domain.
Published changes to your site may not appear on your live site.
Your site may appear correctly in one browser or computer, but not in another.
The SSL certificate will only be issued once propagation is complete.
