Assuming it actually "exists" or is anything but a urban legend, the area is supposed to be between Miami, Puerto Rico and Bermuda, so area starts below Bermuda. The map doesn't show the cable location in detail, but if they pull the cable through or above Bermuda, it seems to narrowingly avoid the area.
