What is DNS Propagation and How it’s works?

What is DNS propagation?

Domains owners change the nameservers to point to the new servers or web hosting provider. The changes consume 24 hours to 48 hours to take effects, and it is called DNS propagation.

Internet service provider nodes around the world update the cache because there have been changes to the DNS information. The old information replaced by the new DNS information of your domain.

Old DNS caches hold the information of your old site, and it may send some of the traffic to the old website, and it can happen between that 48-hours clause. However, the web hosting companies work on your site till it redirects to the new server & site.

Why DNS Caches Clearing Takes up to 48-hours?

A very few people are interested in this topic, but it holds an interesting process that might interest you.

Let’s assume that you opened the site from UAE and the site hosted on USA based provider.

Majority of the masses assume that the site directly connects from web browser to the domain + USA based web hosting provider. However, it isn’t the case at all, and many people suffer from site loading speed because there is a major process behind it.

  1. Enter the domain to open the site.
  2. Browser contacts the local DNS cache.
  3. A request sent to the local Bari ISP.
  4. The request sent to the upstream provider somewhere in Rome, Italy.
  5. The request forwarded to ISP in Hamburg, Germany.
  6. Finally, the request sent to the USA – web hosting server.

The country may differ in the process and the location the visitor surfing the site, but the process remains the same. It is one of the major reasons, why cloud hosting ranks higher because it can load the site faster.

YouStable monitors the changes, and provide you the information. However, no web hosting company holds the responsibility of process duration because they don’t have access to the ISP Nodes.
