In response to the *smart* comments (not repeated here), the percentages
given are of external traffic only. The 2% not accounted for is due to
rounding down the results. I suppose I can do it to more decimal places if
you really want it. Also we do retain lots of our own traffic, but I felt
it was irrevalent for the purposes of this discussion, so retained traffic
was not included in the calculations.
