Saint-Pierre, Saint Pierre and Miquelon

How the Internet Reaches Saint-Pierre, Saint Pierre and Miquelon

Saint-Pierre is the main settlement of Saint Pierre and Miquelon, a French overseas collectivity situated in the North Atlantic Ocean just off the southern coast of Newfoundland, Canada. Despite its proximity to the North American mainland, the archipelago is an isolated island territory, and all international internet traffic arriving in Saint-Pierre does so via a single submarine cable connection to Canada. There is no overland route and no alternative submarine path — the territory's external connectivity depends entirely on this one undersea link.

The cable lands directly at Saint-Pierre, making it one of two landing points for submarine infrastructure within the entire collectivity. The other landing point, Miquelon-Langlade, sits on the territory's northern island grouping and is served by the same cable system.

The Cable Serving Saint-Pierre

The St. Pierre and Miquelon Cable is a 200-kilometre submarine cable that entered service in 2018 and connects the archipelago to Newfoundland, Canada. On the Canadian side, the cable comes ashore at two points: Fortune, NL and Lamaline, NL, both located on the Burin Peninsula of Newfoundland. Within the territory itself, the cable serves both Saint-Pierre and Miquelon-Langlade. This relatively short route across the North Atlantic shelf ties the French collectivity directly into Canadian internet infrastructure, through which onward global connectivity is reached.

Regional Context

Saint Pierre and Miquelon is one of the most lightly connected territories in the Atlantic region in terms of submarine cable infrastructure. The entire collectivity is served by just one cable across two landing points, with an average cable length of 200 km and a first service date of 2018. Saint-Pierre is the primary landing point within the territory, with Miquelon-Langlade being the only other point on the same cable system. There are no additional cables serving the archipelago.

What This Means for Connectivity

Because Saint-Pierre is served by a single submarine cable, all international internet traffic to and from the territory flows through the St. Pierre and Miquelon Cable. Any disruption to this cable would affect every external service accessed by users in Saint-Pierre and across the collectivity. There is no redundant submarine path to absorb traffic in the event of a fault.

The cable's connection to two separate landing points on the Newfoundland coast — Fortune and Lamaline — does provide some degree of geographic diversity on the Canadian end of the link, which may offer partial resilience against localised shore-end incidents. All traffic ultimately transits through Canadian internet infrastructure before reaching the broader global network. Understanding Saint-Pierre's position as a single-cable terminus illustrates how small island territories, even those close to major landmasses, can remain dependent on a solitary submarine link for all external connectivity.
