Subsea Cables & Internet Infrastructure

At the beginning of the third millennium almost all Trans-Atlantic cables directly linked the US or Canada to either Ireland or the UK. Flag North landed at Northport, New York, and Bude, UK. Hibernia North (EXA North) was a rare exception. It came ashore at Halifax and also in Southport, UK. Yellow touched ground on Long Island and at Bude. AC2 came ashore also at Brookhaven and Bude. Hibernia South (EXA South) landed in Halifax and also at Dublin. Finally, Apollo North touched ground at Brookhaven and Bude. Clearly this is inadequate physical diversity in terms of landing points and cable landing stations. It is highly cost effective because subsea cables can share common terrestrial infrastructure, but cost and resiliency are sworn enemies. There is almost always a tradeoff. Almost all Trans-Atlantic traffic went to the 9th floor Telx facility at 60 Hudson and the 111 8th Avenue data centre in Manhattan.
