Once the ship last make it , repair specialists will still have to determine the precise localization of the damage , no easy task since the cablegram must be think from the dark depths of the ocean story .

fixing workers , MIT Technology Review notes , often decide the approximate location of a break by shining a Christ Within down one end of a fiber - optic core and calculate how long it convey for that signal to bound back . All told , the island nation likely wo n’t see internet access restitute for another two to four weeks , a incubus complicating an already take exception humanitarian relief effort .
