Why DNS propagation takes so long?

[Connor]

I wonder why it takes so long for DNS propagation.

[Colton Abbe]

DNS propagation is the time of period in which it takes updates to DNS records to be in full effect across all servers on the web.
Nameservers cache domain record information for a limited amount of time before refreshing, which is why updates don't happen instantly.

How much time does it takes approximately?

[Connor]

It takes anywhere from 15 minutes to 24 hours.

[KelvinSmith]

Yes, and in a few cases, it even takes longer than 24 hours.

Using Google DNS servers on the local PC helps in speeding up the DNS propagation time of the domain.

Is Google DNS a better option?

[Aiden]

Google DNS is likely to have more in-cache, so it is faster and a better option.

[Blake Acy]

The fastest public DNS server i.e. Google DNS was only 10.3 % faster than the default.

[Aiden]

Actually, it all depends on your ISP, which DNS server(s) it uses, and current network conditions.

Is Cloudflare faster than Google DNS?

[Colton Abbe]

Cloudflare is the fastest DNS provider. When compared to Cloudflare DNS, Google Cloud DNS has a slower response time.

[KelvinSmith]

Cloudflare is the most popular DNS provider in the world.

[Connor]

Now, I will use Cloudflare DNS. Thank you all.
