all is conjecturbation.
I did some analysis of this in a presentation at APNIC 33
I agree with Randy that its not "explosive". Its not getting any worse - nor is it getting any better. 50% of the DFZ is more specifics from other advertisements in the DFZ, and this has been true for a decade now. More specific are no more volatile in terms of routing instability than aggregates.
But is it asia-pac? Not really as far as I can tell. I did not add country flags, but if you look at the CIDR report (www.cidr-report.org) I think you'd agree that there is not that much regional concentration in that list - the "bad actors" referred to above really do come from all over the world.
Could we do better? probably. But are we prepared to out some energy behind the wheel to do better? http://www.nanog.org/meetings/nanog53/presentations/Tuesday/Woodrow.pdf has some interesting comments on this.
