Thanks for highlighting the mis-placements of some of the cables. Offices i=

today. There are some other generalizations made on the map, as well, but I=
think
the general concept of their being, along with their general utility in the
universe, comes across just the same. Unless, of course, one is organizing a
fishing expedition;)
Kidding aside, these "errors" are actually intentional, and the publisher m=
akes
no bones about it at the bottom of the page. See disclaimer under the South
Atlantic Ocean:
"Cable Routes do not represent all subsea cable networks and do not reflect
actual location of cables"
