Documents published on November 25, 2014 by Süddeutsche Zeitung revealed more specific details about submarine cables currently tapped by GCHQ. Previous reporting had made it clear that GCHQ had submarine cable taps created in collusion with companies like Vodafone and BT Cable, but not which specific cables. Seeing Telegeography publishes landing point maps and submarine cable maps it seemed like a worthwhile exercise to better understand what, exactly, the reach of GCHQ’s submarine cable tapping might look like.
