Looking at it strictly from a technical level, there is little difference
between a private interconnect and the connection between an ISP and their
upstream provider if they have one. (we might consider debating this
assumption especially in terms of scale :-))
One might as well ask if ISPs are willing to publicly display their packet
drop rates where they buy connectivity from their upstream providers at the
same time one is asking MCI, Sprint, UUNet and ANS for their
interconnection drop statistics.
Might it be easier for a customer of an ISP to get this kind of data from
their ISP? Or not?
