What's really interesing is the fragility of the existing telecom =
infrastructure. These six cables were apparently very close to each =
other in the water. In other words, despite all the preaching about =
physical diversity, it was ignored in practice. Indeed, undersea cables =
very often use the same conduits for terrestrial backhaul since it is =
the most cost effective solution. However, that means that diversifying =
across undersea cables does not buy the sort of physical diversity that =
is anticipated.=20
