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

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