DNS lookups failed for a specific site

I've been using Sprint Embarq CenturyLink DNS IPs for my business network (Windows Server, but it's the provider fault, not the server config):
204.117.214.10 199.2.252.10 and they failed resolving my own (personal) domain. My DNS settings of my server forward there, and I really didn't *want* to change to higher, but it seemed to do a better job choosing a higher level DNS: one of 4.2.2.1, 4.2.2.2, 4.2.2.3, 4.2.2.4, 4.2.2.5, 4.2.2.6 (or I could probably have tried OpenDNS...)
