Greg's Cable Map is an attempt to consolidate all the available
information about the undersea communications infrastructure. The
initial data was harvested from Wikipedia, and further information was
gathere by simply googling and transcribing as much data as possible
into a useful format, namely a rich geocoded format. I hope you find
the resource useful and any constructive criticism is welcome.A mate of
mine did an article on it on his South African Tech site, Check it out if you want more background info.
