Bude, UK Subsea Cable Landscape & Resiliency Concerns

Image
A total of 9 cables land on the beaches near the small town of Bude, UK. There are four operational cable landing stations serving them in the Bude, UK area: two Vodafone CLS, a Colt (former Lumen) CLS, and a BT facility. Please click on https://lnkd.in/gGAP3QMA for a plethora of photos of the cable landing stations. The map illustrates the tendency for telecommunications networks to lack adequate physical diversity to ensure resiliency. Sometimes a laissez faire regulation is not the right approach. Most back haul fibre from the cable landing stations to London probably traverses the single road parallel to the beaches. See below.  When I worked at Hibernia Atlantic as an exclusive sales contractor, we cited the concentration of cables at Highbridge and Bude as good reasons to purchase capacity on the Hibernia North & South cables. North lands several hundred kilometers above Cornwall and at Halifax on the North American side. It was a compelling sales ptich. These cables toda...

Lisbon: An Emerging Subsea Telecom Hub

Marseille was formerly a telecom backwater. It was a minor POP location. But then several things happened. The UK lost its super telecom hub status because it had become almost a single point of failure. Virtually every Atlantic cable linking the two continents landed in Cornwall, England. Secondly, Brexit meant that the UK was no longer part of Europe proper, but rather a political anomaly on its periphery. Thirdly, the Digital Titans recognized that most Asian-Europe traffic Asia was bound for the European continent. Latency could be sharply reduced by going up the Red Sea, across Egypt, and then traverse the Mediterranean to Southern European landings. Finally, traffic originating in Asia and destined for Europe was growing rapidly. So the bureaucrats of the Port Authority of Marseille built segregated landing facilities and sea lanes. Permit application process was streamlined so only one office was involved. Secure facilities were set up for power feeds. By the end of 2026, 16 cab...
