Transaction Network Services (TNS), a provider of trading infrastructure for hedge funds and other investors, has launched services at the Equinix ZH4 colocation data centre in Zurich, providing ultra-low latency connectivity to the SIX Swiss Exchange.
The move expands TNS’ presence in key financial hubs, complementing its existing colocation services in London, Frankfurt, and other major European exchanges. By establishing a foothold in Zurich’s financial district, TNS enables market participants—including proprietary trading firms, market data vendors, and exchange members—to access Swiss equities and derivatives markets with enhanced speed and efficiency.
The deployment offers TNS’ managed hosting and Layer 1 connectivity, which delivers sub-microsecond trading speeds—crucial for firms seeking to minimise latency and maximise market access. The colocation at ZH4 provides direct access to SIX Swiss Exchange, home to over 60,000 equities, bonds, ETFs, and more than 250 crypto products.
“Adding our colocation in Switzerland to the TNS European network means that their customers can benefit from direct access to SIX Swiss Exchange, a key financial hub,” said Santiago Ximenez, Head of Colocation and Market Access at SIX in a press statement.
The expansion comes amid rising demand for cost-efficient, high-performance trading infrastructure in Europe. TNS, as a registered data vendor and application service provider with SIX, offers solutions at a lower total cost compared to firms building in-house infrastructure.
The Zurich launch is part of TNS’ broader European expansion, which already includes colocation services at major exchanges such as BME, Cboe Europe, Deutsche Börse, Euronext, LME, Nasdaq Nordic, and LSE.
TNS’ global infrastructure supports more than 5,000 financial market endpoints and a 125-point-of-presence footprint, offering colocation, cloud services, market data, and VPN solutions through its Infrastructure-as-a-Service (IaaS) portfolio.
