What I was trying to say is that not all large transit 
providers are so-called "Tier-1's", as was asserted.

To say that all networks in the world that are not 
"upstream-free" should just point 0/0 | ::/0 to some Tier-1 
is unreasonable.

Many markets claim to be Tier-1 in their areas of operation, 
but they buy enough transit to fill up a hole. In their 
eyes, they are not "non-Tier-1's", and what's worse, they 
probably don't connect to so-called "Tier-1's", directly.

Mark <= who isn't a fan of the "Tier-X" classifications.
