Zayo Activates Monet Route Between U.S. and Brazil

Zayo has activated capacity on the Monet subsea cable, giving the company a third diverse route between the United States and Brazil. The service joins its existing routes on Seabras-1 and GlobeNet, expanding the choices available for traffic moving between the two countries. Zayo says the addition strengthens the Miami–São Paulo corridor with more bandwidth and resiliency. For customers, the announcement concerns capacity that is already activated, rather than a proposed cable awaiting construction.

In São Paulo, the Monet route connects with Zayo's metropolitan network ring and Equinix facilities SP2, SP3, and SP4, as well as the B3 stock exchange. In North America, it connects to Zayo's network, including MIAX Sapphire in Miami and the Spread Network linking Chicago and New York. Those connections give the submarine route a role beyond carrying traffic across the ocean: they connect the international corridor with data center and financial market locations on land, where customers need access to applications and counterparties.

The intended customers span cloud and artificial-intelligence providers, multinational businesses, financial institutions, carriers, and content companies. Their requirements differ, but additional routing options can help businesses plan how to move traffic and maintain connectivity when a particular path is unavailable. Route diversity is therefore a meaningful part of the announcement, not simply another name on a network map. Zayo is adding Monet alongside two other subsea routes, giving customers another option for international connectivity without presenting the activation as the construction of a new submarine cable.

Zayo says its broader network reaches more than 1,400 data centers, 400 metropolitan markets, and 90,000 enterprise locations directly connected to its network. That footprint provides context for how the Monet capacity fits into its wider services, rather than describing the reach of the subsea cable alone. The current milestone is operational activation of the additional capacity. The announcement does not set out a new construction milestone, so the immediate significance is the availability of an additional U.S.-Brazil route and its connections into existing networks.
