You dont? wasnt it in April? and John was talking about the same thing.
Personally, we dont see problems like this 'anymore'. We filter on any and
all reserved ASpaths. We also filter on RFC1918. And since we filter it,
we dont worry about it anymore. Personally, I applaud Verio for all the
filtering they do (and anyone else that does it).
This was also posted in April in regards to filtering peers (you can
filter your transit providers).
