Dyn Research, Doug Madory, has a good blog post looking at the physical 
threats affecting submarine cables; as well as covering recent historical
submarine cable outages due to human action.

And also a very nice infographic by Caroline Troein, Tufts University, 
show global submarine cable vulnerable points.

Overall, Internet architecture has demonstrated resiliance to physical 
layer disruptions, but it has not proven as resliant to logical layer
