DNS Change

How long does it take?

[Edge]

I'm planning on submitting a DNS change Tuesday, next week. How long does it take for the world to migrate to my new DNS address?

This used to take upto a week several years ago.

Hosts still keep saying it could take up to several weeks. But, it normally happens in a few hours. Trusting, like you did, what the host said I waited for several days and still couldn't see my site in the browser. After the two weeks passed I phoned the hosts and they admitted, "er, it looks like there is a zoning issue at our end". So I was waiting all in vain, the DNSes had resolved but first line support kept saying effectively that it was too early to keep phoning them about this.

a few months ago it used to take 24-48 hours.

Most recently, on .com domain names in particular, I've been seeing near instantaneous propagation.

I would make the nameserver changes, click save, browse to the domain name and the changes had already taken place.

Very neat change that seems to have been made at the registry level.

are you talking about a DNS or a domain change? I have my own DNS server and slave DNS in a second datacenter pointing to 6 webservers for 1 domain with TTL=300 - so after 5 to 10 minutes 99% of all internet users (even repeat visitors) learn about IP changes. Before a major change I would set the TTL to 60. Search for "dynamic DNS solutions"

Yes, I mean a DNS change. I actualy did the change this morning, but have not seen the propagation.

I double checked about 5:00 pm est to ensure I had my priamry and secondary right.
