Telcos and dark fibre

My institute's magazine is superb - unlike most industry/free rags it is readable and reminds me of how good Scientific American was in the eighties. One of the best articles last week was on the amount of dark fibre there is in the world. The link (above) is to the article;

The telecommunications industry built too much fibre-optic network capacity during the 1990s. Companies such as KPNQwest, FLAG, Global Crossing and Tyco borrowed too much money and laid too much fibre, and suffered the consequences. Is that over-capacity still present? It’s not clear.

This diagram is missed out of the HTML version of the article.
