Where is the internet most vulnerable?

The Asia-Africa-Europe-1 internet cable travels 15,500 miles along the seafloor, connecting Hong Kong to Marseille, France. As it snakes through the South China Sea and toward Europe, the cable helps provide internet connections to more than a dozen countries, from India to Greece. When the cable was cut on June 7, millions of people were plunged offline and faced temporary internet blackouts.
