Traffic asymmetry across peering connections
was what lit the fuse on this whole powder keg,
if I understand correctly; at the point the traffic
went asymmetric, the refusals to augment
capacity kicked in, and congestion became
a problem.

I've seen the same thing; pretty much every
rejection is based on ratio issues, even when
offering to cold-potato haul the traffic to the
home market for the users.

If the refusals hinged on any other clause
of the peering requirements, you'd be right;
but at the moment, that's the flag networks
are waving around as their speedbump-du-jour.
So, it may be very "1990", but unfortunately
that seems to be the year many people in
the industry are mentally stuck in.  :(
