If you're changing the host records in the name server and the DNS, then, depending on how the DNS is set up, it can take as little as 15 minutes.

For example, I moved one of my (nonadult) servers from another provider to NatNet last night. It was a discussion board, and I turned off the discussion board, made the DNS change in Enom's DNS, had NatNet move the data to the new server, updated the DNS, and in about 20 minutes, everything was online and working on the new server.

But unless the old DNS removed the entry for your site from its records entirely, you should NEVER get a "server not found."

Hope that helps!
It helps a little...

Here is what I did, maybe you or someone else can see where I went wrong.

I have a site hosted at AAA. The domain is held by ezdomainname.com. I built a new site on a new server hosted at BBB. I went into ezdomainname.com and clicked on "Nameservers" and changed them from NS1.AAA.COM to NS1.BBB.com.

Right away, I could no longer see the site, and got the "Server can not be found" page on my browser.
