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.
Telefónica, a Spanish multinational telecommunications company founded in 1924, operated a content delivery network (CDN) as part of its broader telecom services. The CDN focused on delivering content across Europe and Latin America, leveraging its extensive network infrastructure. It served enterprises, media companies, and telecom partners but ceased CDN operations as part of a strategic pivot away from certain business units. As of 2025, Telefónica’s CDN is defunct, with the company focusing on core telecom, IoT, and AI services.

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.
Telefónica’s CDN leveraged its telecom backbone, offering low-latency delivery in Europe and Latin America. The service supported instant cache purging and API-driven configurations, as noted in historical reports. The decision to sunset the CDN aligns with Telefónica’s broader strategy to exit non-core markets and invest in 5G, IoT, and cloud security. No conflicting reports suggest a revival of the CDN.
