Yes ok I see the difference now :)

Thanks for taking the time to explain.

Other than getting the updated zone files when they are published, there should be no reason for a fully-slaved t2 server (where they are slaving ALL of the TLDs) to query a t1 server.  But if you are comparing a minimal slaved t2 (which only contains the root zone and the dns zone), then I agree there would be very little difference between that and a hints config.

Yes actually I am reading your shiny new wiki pages (nicely written btw) and I saw you are recommending the slave config for public T2 servers, that's why I am asking.

The difference in behaviour is minimal because as far as I have read, both servers will query the T1 when they don't have the answer, then store or cache it locally, and answer as authoritative. A difference in behaviour does appear when the T1 is offline though, where the slave continues to operate for a longer period of time. I have just read a benchmark concluding there is not much difference in traffic, but the response time can be a bit better on slave than hint.

I am sticking to my slave config for now, as you recommend.
