Subsea Cables & Internet Infrastructure

EXA has emerged as the dominant player on the Atlantic routes. Its original subsea network consisted of the the highly diverse North and South Hibernia cables complemented by the much faster and younger Express cable.  North EXA cable was RFS 2001. It connects London & New York via landings highly diverse to its competitors. North lands in Canada at Halifax and at Southport, UK. In contrast, most Atlantic cables land near New York City and in Cornwall near Bude. North's diversity makes it an excellent choice for network planners focusing on resiliency. Obviously, the cable's latency is high, but that is generally the tradeoff one must accept to achieve physical diversity. I think the RTD 60 Hudson/Telehouse London is probably 76 ms. dfs South EXA cable was also RFS 2001. It lands at the same CLS as North on both sides of the Atlantic. I believe the latency is slightly higher.  Express was built much later (RFS 2015). It is designed to be the lowest latency path from LD4 Slo

The Atlantic at the 100G level ranges from $4K to $6K MRC. The cables deployed at or around the time of the New Millenium vary from $3,800 to $5K. Generally, new cables like Marea and Dunant command a premium because they directly connect Ashburn Equinix to Continental Euroipe with both Ashburn Equinix and at least two Paris Equinix facilities onünet. Both bypass Ireland and the British isles. So expect to pay in the $5K to $6K range on 2 or 3 year terms. And yes, you should pay the premium because Marea, Dunant, Anjana, and Nuveem all dramatically improve resiliency. The NYC/London cooridor is congested with most UK landings in Cornwall at Bude. Furthermore, UK surveillance of undersea cables is well known.  Any saavy buyer should be riding both NYC/London cables and also cables like Dunant and Marea that directly link Ashburn Equinix to the European continent. This physical diversity is not a luxury; it's essential. A special mention goes to EXA Express for NYC/London which is a
