The answer
870,000 miles
Roughly 870K.
Around 870,000 miles of fibre-optic cable lie on the sea floor, enough to circle the Earth 35 times. Over 95% of all intercontinental internet traffic runs through them, not through satellites, and they are cut by ships’ anchors and fishing gear about 200 times a year.
