I have been assuming they were only open recursive resolver nameservers...I think perry's question is: "Can you show me which networks youtraversedand which instance of the service you were talking to at the time of the problem?" (or 'now' if the problem is persisting)Sure, Chris. But since Perry's problem is *inability to resolve names in google's

public zones*, the *path to the ZONE servers* is the thing diagnostics would require a trace to, no?
I think, from some troubleshooting with blair yesterday he was having some odd problems with queries to google-public-dns (gdns), where everything he asked came up servfail. I wasn't able to repro this, which was annoying ;( We (perry/others) were interested in verifying that something odd wasn't happening between blair and the server answering his question(s)...
If 8.8.8.8 doesn't *answer* for "google.com" (and no one's told me it has), then how you get there is irrelevant.
8.8.8.8 is just an open resolver... oh, jabley replied as well (alway a cogent reply from him)
