Why should the testing stop (and what sort of testing did Cymru do?)? 
>From my experience with 69/8 space (69box.atlantic.net), I can tell you, 
networks with outdated bogon filters will always exist.  If Cymru is 
providing or can provide a tool for people to use to test/verify that 
certain networks have such filters affecting the above blocks, then it's 
still a useful service.
