The Grand Banks earthquake breaks cables in sequence

node

An earthquake at the southern edge of the Grand Banks, south of Newfoundland, triggered a large submarine slope failure. Cables in the immediate area broke at once; further out, transatlantic telegraph cables broke one after another, progressively further from the source, over a period of about thirteen hours. Twelve cables were broken in all. The sequence was recorded because cable stations knew precisely when each circuit died, and it became, more than twenty years later, the evidence from which turbidity currents were inferred.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
