I know someone who'd happily sink both the /24's in question.. if apnic's
interested.

Hello,
After 1/8 was allocated to APNIC last week, the RIPE NCC did some
measurements to find out how "polluted" this block really is.
See some surprising results on RIPE Labs:

Please also note the call for feedback at the bottom of the article.

The most surprising thing in that report was that someone has an AMS-IX
port at just 10 megs.  It would be nice to see an actual measurement of
the traffic and daily/weekly changes. A breakdown of the flow data by
source ASN and source prefix (for the top 50-100 sources) would also be
interesting.

There was a call on the apnic list for someone to sink some of the traffic.

I'd like to see someone capture the data and post pcaps/netflow analysis,
and possibly just run a http server on that /24 so people can test if their
network is broken.

I've taken a peek at the traffic, and I don't think it's 100's of megs, but
without a global view who knows.
