Tampnet builds, owns and operates its own terrestrial and subsea network delivering a unique path between the Nordics and the United Kingdom. The redesigned and optimised ULL route between Stockholm and London leverages state-of-the-art optical switching and a proprietary wet path across the North Sea on Tampnet South. This unique route and enhanced design offers the lowest latency path available on the market today. The newly optimised ULL route offers guaranteed SLAs and diverse subsea routing, with protection for the highly competitive and regulated Fintech sector.

“For the past five years Tampnet has offered low-latency connections between Stockholm and London to the High Frequency Trading (HFT) community only through partners,” comments Cato Lammenes, Managing Director of Tampnet Carrier. “Redesigned and optimised for High Frequency Trading (HFT) to achieve the lowest possible latency for Ethernet or Wavelength services, we reiterate our commitment to continually improving our network routing and design capabilities. Now we are bringing our network solutions directly to financial services customers for the first time.”

Tampnet Carrier’s optimised route cements the company’s position as the leading ULL network and subsea provider between Stockholm and London, now available directly to the market with the highest level of SLAs guaranteed.
