... or perhaps on an internet where many network owners block / police /
throttle packets by source or destination, implementing CGN or stacking
thousands of websites behind one IP address are poor solutions to the
connectivity problem.

My only issue is the lack of information provided when blocks go into
place.  I would love to see networks provide information publicly that
shows what is being blocked along with a description of why.  A history
that extends for a few days would be a bonus.
