I'd suggest one avoid using non-local or low latency dns servers (Unless: the ones nearby are untrustworthy, e.g. in a country where they have a habit of messing with dns or firewalling its citizens). Me personally, i use my local isp's one, until Google switch to having resolvers in Australia. <div>

I was under the impression google had a cache in Perth as well, they<br>
certainly have peered via waix.<br>

when I do the math on what I see to google (0-1 msec) and I add what I see<br>
to internode LNS in Adelaide (20ms) then I do an LFT to your PPP which shows<br>
a differential to the LNS of another 24ms for your last hop, when we add the<br>
internode latency to Adelaide, 20 + your last hop latency of 24 =<br>
44-45ms..... which is the exact figure you are coming up with?<br>
