It seems the problem isn't at godaddy but rather somewhere in between, 
as bind list users said a couple of times, some of them get the reply using

dig +dnssec @ns33.domaincontrol.com. replacementservices.com.

The only workaround for now seems to be

forward-zone:
         name: "replacementservices.com"
         forward-addr: 8.8.8.8
         forward-addr: 8.8.4.4
....

but doing this on our scale is quite a workout as the servers provide 
recursive replies for about 200k clients.
