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.
