Yep. For me, it doesn't work when using the DNS of my ISP, but it works just fine when using one of Google's DNS servers or clrghouz.bbs.dege.au directly:

Not sure of the best way to pinpoint this, though. Could there be something "firewallish" preventing some of the "upstream" DNSes from getting answers from clrghouz.bbs.dege.au? Or perhaps they have restricted the allowed queries... Strange.
