Not at all. The pool was delegated. It is the responsibility of the pool
operators to maintain the DNS Records and of the operators of those
systems that provide pool service to update them as necessary.

One of the items on my work list is to implement the code to have ntpd
check each address returned and use it if NTP service is available and
to allow you to specify directly how many to use from the one address name.
