Why does the website from my old server still appear after I’ve made changes to the DNS?

It’s possible that, during the propagation period (up to 24 hours), the old server content is still displayed to some of your website’s visitors. This is mostly due to the DNS cache of the visitor’s Internet provider, but sometimes the reason is that the pages that are stored in the Internet browser cache are those that are displayed, so your browser cache needs to be cleared.
