when there is a change in the domain info?

[Evren Yurtesen]

When the owner changes the name servers etc. of the domain why the
technical contact does not receive a notification? I believe it is
necessary because the person might change ISPs without telling anything to
the original ISP and we wouldnt even realize anything plus include the
wrong DNS information in our servers  pointing to our web servers perhaps
which would cause all the users connected to our network would have stale
pages etc.
