Connecting a domain to a website typically involves updating DNS settings, which can take some time to propagate across the internet. The process usually takes anywhere from a few hours to 48 hours for the changes to fully take effect. However, it's important to note that in some cases, it might take up to 72 hours for the changes to be visible worldwide, and some domain registrars might take longer to update their DNS records.
During this propagation period, some users might see the new website when they access the domain, while others might still see the old website. This discrepancy is due to the distributed nature of DNS updates.
If you're concerned about the progress of the domain connection, you can check with your domain registrar or your website hosting provider for more specific information based on your situation.
