CentOS - Sep 2014 - Could not resolve host: mirror.centos.org

There seems to be a problem with my local dns server resolving 
mirror.centos.org.
I know something about dns but obviously not enough to figure out what 
might be wrong here or how to fix
this in bind configs. The SERVFAIL errors below seem to be related to 
AAAA and MX queries for the domain.
Please advise. TIA.


# host mirror.centos.org 8.8.8.8
Using domain server:
Name: 8.8.8.8
Address: 8.8.8.8#53

mirror.centos.org has address 66.109.26.212
Host mirror.centos.org not found: 2(SERVFAIL)

Try asking the correct type (A record only) and you'll have the correct
answer : the three PDNS servers having delegation for mirror.centos.org
will only answer for A records (we have obviously no MX record for
mirror.centos.org and, unfortunately, no AAAA records for those machines
either)

PS : host is considered "deprecated" so switch to dig instead ? ;-)
