The story
The London-to-Frankfurt financial corridor is Europe's primary trading artery, interconnecting foreign exchange, equities, and derivative venues across Equinix LD4 (Slough), Telehouse North (London Docklands), and Equinix FR2 / Interxion (Frankfurt). Optical network providers such as euNetworks engineered dedicated subsea English Channel crossings (Scapa / Superhighway) and straight-line terrestrial fiber through France and Belgium to cut round-trip latency to ~4.1 milliseconds, serving the ultra-fast automated market makers arbitrageing Euronext, LSE, and Deutsche Börse.
