The odd thing about this situation though is the geographic location of Brooklyn: on an island. Why would a significant amount of traffic from outside Long Island be going across the harbor to Brooklyn, especially given all the major switching facilities in Manhattan (closer to shore).

What makes you think it is only connected to Manhattan? Long Island has submarine cables connected to New England, various points along the East Coast south of NYC, and several transatlantic cables.
