Hi I want to make MIRROR Hosting
on my general website.

I want to make MIRROR between 2 servers
one in Bulgaria and one in USA (The Planet)

The problem is that I do not know how
to switch the DNS servers
to become this service available ...

The Mirror hosting is a service, when one site
is hosted on 2 hosting servers in (for example: 2 continents)
EUROPE - USA ...
When the visitor is from Canada, he will open the web site
from the web server that is near to the client.
If the client is from Greece, he will open the web site
from the Bulgarian server (becouse the website visito will be nearly to the
world peering internet map and to the fastest for him hosting server)

If someone can help me, please write here,
also owners of other hosting companies with big experience in the
Webhosting Industry can help me here ...

Thanks,

You can do this in one way as far as i know, you can point the domain to 2 ip address, let me give you an example.

-bash-2.05b$ host yahoo.com
yahoo.com has address 216.109.112.135
yahoo.com has address 66.94.234.13
yahoo.com mail is handled (pri=1) by mx3.mail.yahoo.com
yahoo.com mail is handled (pri=5) by mx4.mail.yahoo.com
yahoo.com mail is handled (pri=1) by mx1.mail.yahoo.com
yahoo.com mail is handled (pri=1) by mx2.mail.yahoo.com
-bash-2.05b$

Mail is better to handle it on one server, maybe on your US server.
To do this you have to edit yourdomain.com file from /usr/local/psa/named/run-root/var (if using plesk). If you are using Cpanel just do locate yourdomain.com and edit it.
Add this in your file:

yourdomain.com. IN A ipaddress1
yourdomain.com. IN A ipaddress2
www.yourdomain.com. IN A ipaddress1
www.yourdomain.com. IN A ipaddress2

This should do the trick.
