So, I am not sure I fully follow the issue.

Here, the time nslookup is fast (for now). 
And the dnsmsq cache use google dns rather than iweb provided one.

So when you say "upstream dns server is bad", which one do you mean

( cloud.gluster.org is handled by rackspace, we could move to named
managed locally, but then, this will not be self service anymore )
