What Is DNS Propagation and Why Does It Take so Long?

What is DNS propagation?

To speed things up on the internet, each Internet Server Provider (ISP) caches their DNS records. They create their own copy of the master record and access it locally to search for a website, each time someone tries to view it. This procedure speeds up internet activity, reduces the traffic and thus help the ISP work faster.

The slow updating of the server cache is called propagation. When you update the nameservers for a domain, it may take up to 12-24 hours for the change to take effect over the internet. This period is called DNS propagation.

How Long is the Waiting Period?

Name server and DNS zone changes can typically take 12 to 24 hours to take effect, but they are known to take as long as 48 hours to go into full effect.

Nothing can be done to speed the propagation process, however, it is recommended that you plan for propagation ahead of time to minimize the effects of downtime.
