Overview

Hibernia Networks, formerly Hibernia Atlantic, was a US-based provider of global telecommunications and CDN services, operating subsea and terrestrial fiber networks. It served financial markets, media, and telecom providers with low-latency connectivity, including the Hibernia Express transatlantic cable. Acquired by GTT Communications in January 2017, its CDN services, including HiberniaCDN, are no longer independently offered, and the brand is defunct.
NTT Communications, a subsidiary of Nippon Telegraph and Telephone Corporation, provided a content delivery network (CDN) through its Smart Data Platform, powered by EdgeCast, offering global content delivery for enterprises. The service, launched in 1999, supported various industries with robust network infrastructure until its deprecation in 2025. Following the sale of Edgio’s CDN business, NTT Communications announced the shutdown of its CDN platform, with services ceasing on January 15, 2025. Customers were advised to migrate to Akamai to maintain CDN functionality.

History & Notes

Hibernia Networks operated a global network across North America, Europe, and Asia, with key cable landing stations in Canada, the US, Ireland, and the UK. Its Hibernia Express cable was notable for sub-59ms latency between New York and London, targeting financial and media sectors. After the 2017 acquisition by GTT Communications, Hibernia’s infrastructure was absorbed, and no public documentation indicates a revival of its CDN services. A 2019 subsea cable cut led to a legal dispute with a customer, highlighting operational challenges pre-acquisition.
NTT Communications leveraged its telecom expertise to deliver CDN services, primarily targeting enterprise clients in Asia and globally. The partnership with EdgeCast enabled features like instant purge and real-time logs, but the service’s reliance on Edgio led to its discontinuation after the 2024 asset sale to Akamai. Some customers may still access archived documentation or support through NTT’s sales channels during the transition period.
