is it -really- global?

anyone keeping track of their RTTs?
i'm finishing up some work on latency and all i have are my numbers.
its going to be highly variable based on where you are and where you go,
but it would be nice to have other sets of numbers.

roughly my targets are ::

43% are "cloud" oriented - CBN stuff that tried to place bits near me
22% are US/CA targets
14% are kcj
12% are eu
4% are africaan
5% are other

and the source moves, East/Best coast of the US, Africa, Japan, NZ


only intl links on which smokeping shows anything is ashburn to tokyo.
but that only covers us, joburg, linx, tokyo

Anything that can explain the 50 ms rtt increase during 1 month by the end of the year?
