Yes, I know; I did read that in context and understand the point
the original author was making.  I probably should have made that clear.

True enough.  But its continued presence, *seven years* after it was
well-known to be a serious problem, tells us that Comcast either (a) can't
or (b) won't run its network properly.  So given this prima facie evidence
of either (a) systemic, chronic incompetence or (b) systemic, chronic
negligence, I think it's reasonable to wonder how many other aspects of
their operation are just as horribly broken, and what the impact of
that on their ability to carry steadily-increasing traffic might be.
