The fastest paths across the Atlantic
EXA Express is the fastest route between New York and London at under 60ms. AEC-1 is the second at 69.2ms. Both run on systems we own outright.

Latency and protection
Faster paths, fewer surprises.
Protection at every layer
Nine diverse transatlantic systems, meshed with long-haul and metro protection, so multiple alternative paths exist at each layer rather than only across the ocean.
Exchange connectivity
Your gateway to the exchanges.
Direct, compliant and secure connectivity to 25 financial exchanges across North America and Europe, with colocation and cross-connects at the exchanges themselves. Beyond those, more than 130 major exchanges are reachable across the wider platform.
Where you can reach
25 exchanges across 11 countries, around 60% of global market capitalisation, plus eight crypto exchanges, trading houses and brokerage firms on the same fibre.

SERVICES
What you can buy on these routes.
Ultra-low-latency wavelengths
10G, 100G and 400G on the fastest paths we run, with fixed routing so latency doesn't drift.
Exchange colocation and cross-connects
Rack space inside the exchanges themselves, cross-connected to the network.
Fixed route Ethernet
Uncontended, with deterministic routing, for exchanges where a wavelength is more than you need.
Dark fibre
Dark fibre on the same routes, for firms running their own equipment who want to control their own latency budget.
Problems we solve
Typical problems, and how EFN answers them.
Built for backbone: space at cable landing stations, amplifier sites and PoPs on the network, designed around the equipment that runs it.
A proprietary trading firm wants the fastest, most consistent New York to London path
EXA Express, on fibre we own outright. Lowest available latency, and deterministic, so it behaves the same way every day.
A bank needs resilience and compliance, not just speed, across the Atlantic
Fully diverse protected routing, with the diversity documented and evidence for the regulator.
The overlap map shows you exactly where we already are, and how fast we can extend to where you’re building next.
One platform reaching 25 exchanges. Multi-exchange distribution without assembling it from several providers.
Frequently asked questions
What is the New York to London latency?
EXA Express delivers the lowest-latency fibre route between New York and London, under 60ms. AEC-1 follows at 69.2ms, and Slough to Secaucus is available from 60.0ms round trip.
Does EXA Infrastructure own the routes?
EXA Infrastructure owns and operates EXA Express and AEC-1, the two fastest transatlantic paths, along with the terrestrial fibre and duct they connect into. Across the wider subsea estate, 18 systems are held as a mix of wholly owned, consortium and long-term IRU.
Is DORA evidence available?
Route diversity is documented per circuit, so physical path separation can be evidenced rather than asserted. Tell us which artefacts your DORA reporting requires and we will confirm what we can provide.
Which exchanges can EXA Infrastructure reach?
EFN connects 25 exchanges across 11 countries, representing around 60% of global market capitalisation. Beyond the EFN platform, more than 130 major financial exchanges are reachable across the wider network.
How are paths protected?
Nine diverse transatlantic systems, with protection paths at metro and long-haul level as well as across the ocean. Diversity is engineered into the network rather than arranged contractually, and documented so you can verify it.
