SOMEBODY is still talking to me:

I'm glad to see my upstreams don't have broken bogon filters.

I would have hoped that people who are enlightened enough to run IPv6  
would also know that you should either keep your bogon filters up to  
date or don't have any in the first place, but I guess that was too  
much to expect.

You can see what happens with my 6bone connectivity by pinging/ 
tracerouting 6bone.muada.com, by the way. I'll be interested to see  
whether UUNET/MCI/Worldcom/Alter.net makes good on its promise to  
remove 6bone space after 6/6/6.
