Overview
Hibernia Atlantic was the earlier operating name of Hibernia Networks, a US-owned telecommunications provider that built its business around international fiber connectivity. The company operated submarine and terrestrial network infrastructure linking North America with Ireland, the United Kingdom, and mainland Europe, later extending connectivity into major Asia-Pacific markets. Its network architecture included self-healing rings intended to improve resilience and service continuity across long-distance routes. The company’s principal infrastructure was the Hibernia transatlantic cable system. The original system was built in 2000 by Tyco Submarine Systems for 360networks. After 360networks entered receivership in 2001, the cable assets were acquired in 2003 and began carrying traffic in 2005. Hibernia subsequently developed and marketed the route as part of a broader communications platform, operating cable landing stations in locations including Halifax-area Herring Cove in Nova Scotia, Lynn in Massachusetts, Dublin, Southport in England, Brean in Somerset, and Coleraine in Northern Ireland. Hibernia sold wholesale and enterprise network capacity rather than consumer telecommunications services. Its portfolio included wavelength services from 2.5 Gbit/s through 100 Gbit/s, Ethernet connectivity from 10 Mbit/s through 100 Gbit/s, traditional SONET/SDH services, IP transit, managed network services, video transport, and customized international capacity. The company also targeted financial institutions and trading firms that valued predictable, low-latency routes between exchanges, data centers, and metropolitan network hubs. A major strategic initiative was Project Express, announced in 2010 as a new transatlantic cable between the New York metropolitan area and Slough in the United Kingdom. The project was designed for high capacity and very low latency, with a publicly stated target of less than 60 milliseconds. Hibernia announced construction with TE SubCom in 2014, describing the approximately 4,600-kilometer system as a direct, low-latency fiber path between New York and London. The project reinforced the company’s focus on financial-market connectivity and high-performance international communications. Hibernia expanded through acquisitions and network partnerships. It acquired MediaXstream in 2009, bought Media Connect assets from TeliaSonera International Carrier in 2012, and acquired Atrato IP Networks in 2013. The Media Connect transaction strengthened its managed video transport capabilities in Europe and North America, while Atrato added IP and transit services. In 2011 the company announced network expansion into Tokyo, Singapore, and Hong Kong. It also supplied capacity and connectivity to infrastructure and data-center providers such as Voxility. In January 2017, GTT Communications acquired Hibernia for an initial announced price of $590 million, later reported at $607 million. Hibernia was absorbed into GTT, ending its existence as an independent company and bringing its transatlantic assets and services into GTT’s global communications network. The Hibernia Atlantic name therefore represents both a submarine-cable brand and the predecessor identity of the broader Hibernia Networks business.
History
The Hibernia business originated in the development of a transatlantic submarine cable system during the telecommunications infrastructure boom around 2000. Tyco Submarine Systems built the system for 360networks, but the original owner entered receivership in 2001. The cable assets were acquired in 2003 and began carrying traffic in 2005. Hibernia Atlantic became associated with the route and developed it into the foundation of a wider international telecommunications network. The network connected North America with Ireland, the United Kingdom, and mainland Europe through submarine and terrestrial infrastructure. Its landing-station footprint included Herring Cove in Nova Scotia, Lynn in Massachusetts, Dublin, Southport, Brean, and later Coleraine in Northern Ireland. Hibernia used self-healing ring architectures and optical transport systems to provide resilient international connectivity. Services ranged from traditional SONET/SDH circuits to Ethernet and wavelength products reaching 100 Gbit/s. In 2007, Hibernia selected Huawei Technologies USA to upgrade approximately 24,520 kilometers of submarine and terrestrial network across North America and Europe. The company expanded its commercial scope in 2009 by acquiring MediaXstream, a managed network-services provider. It also concentrated on customers for whom latency and route quality were commercially important, particularly financial institutions, trading firms, exchanges, and data-center operators. Hibernia announced Project Express in 2010. The proposed system was intended to connect the New York metropolitan area with Slough in the United Kingdom using a high-capacity, low-latency route. Hibernia stated that the system would target less than 60 milliseconds of delay and a capacity of approximately 8.8 terabits per second. In 2011 the company extended its network reach into Tokyo, Singapore, and Hong Kong, broadening its geographic proposition beyond the North Atlantic. A 2012 transaction involving Media Connect assets from TeliaSonera International Carrier strengthened Hibernia’s presence in managed digital-media and video transport. The assets covered Europe and the United States, and Hibernia described the resulting network as one of the larger dynamic transport mode video networks. That same year, Hibernia contracted with Voxility to provide European and transatlantic capacity connecting data centers in North America, the United Kingdom, and Germany. In 2013, the acquisition of Atrato IP Networks added IP and transit services. In 2014 Hibernia and TE SubCom began construction of the new Project Express submarine system. The approximately 4,600-kilometer cable was designed as a direct, low-latency fiber path between New York and London and reinforced Hibernia’s emphasis on financial-market connectivity. The project later received the 2016 GTB Innovation Award for Fixed Infrastructure. Hibernia was privately held and was previously associated with Columbia Ventures Corporation and Constellation Ventures Partners. On January 9, 2017, GTT Communications acquired the company for a reported $607 million, following an initially stated price of $590 million. Hibernia was absorbed into GTT, ending its independent operation and leaving Hibernia Atlantic as a historical name for the cable and network-services business.
