I think running something like DSC to analyze this would be a good thing 
to do.  That, or I can make a plug for all AS112 operators to run ncaptool 
and funnel the results of that directly to ISC for further analysis. 
(Come to think of it I need to put Frank's tutorial online too.)

As Joe already stated, exposing the badness to the light may do some good 
to cure it.  Besides, I got tired of being asked by people sitting behind 
NAT boxes with poorly administrated DNS servers why 'their Internet was 
slow'.
