When you update the nameservers for a domain, it may take up to 24-48 hours for the change to take effect. This period is called DNS propagation.
In other words, it is a period of time ISP (Internet service provider) nodes across the world take to update their caches with the new DNS information of your domain.
Due to DNS caches of different levels, after the nameservers change, some of your visitors might still be directed to your old server for some time, whereas others can see the website from the new server shortly after the change.
Why does it take up to 72 hours?
Let’s imagine you live in Bari, Italy, and you just have changed the nameservers for your domain that is hosted in Phoenix, USA.
When you open your domain in a web browser, your request is not going to the hosting server directly, it has to pass through several ISP nodes first. So your computer starts by checking the local DNS cache, then the request is sent to your local Bari ISP. From there, the request goes to the upstream provider in Rome, Italy, then connects to the ISP in Hamburg, Germany. After that, the request is sent to the first receiving point in the USA – New York, NY and ultimately, to the ISP in Phoenix, AZ. Here is an example of the request trace – the number of ISP nodes and their location will vary in each particular case:
