Zayo Group Holdings, Inc. has announced success-based expansions of its fiber networks in four European markets, including London, Paris, Dublin, and Amsterdam. Driven by demand from hyperscale, cloud and data center providers as well as enterprise customers, these strategic expansions will deliver fast, high-capacity fiber to key centers of technology and commerce.

In London, Zayo is building a new fiber route from Hatfield, Hertfordshire to Stratford, East London, as part of a strategic ring outside of the city. The new route will support a number of current and prospective customers with high-performance fiber, providing a new option for long haul routes from Dublin to Amsterdam and enhanced diversity for data center customers in Enfield. The expansion adds to Zayo’s greater London footprint, which includes unique diverse and triverse routing options via traditional conduits in footways and carriageways as well as London’s largest sewer-based fiber network.

In Paris, Zayo is expanding its fiber footprint in La Defense, a major business district west of the city limits. Zayo currently serves dozens of customers located there over its high-capacity fiber network. The new network extensions will expand Zayo’s reach to major office buildings in the district. La Defense is one of the largest hubs of business and commerce, including both French businesses and multinationals.

In Dublin, a multinational company has selected Zayo for a fully diverse dark fiber ring around the metro area. The high-fiber count solution will significantly improve latency for the customer, with the potential for follow-on sales to many companies that have a presence in Dublin or are considering investment and relocation in Ireland. The new routes complement Zayo’s existing T50 fiber network in Dublin.
