NL-ix Acquires STHIX in Major European Expansion
Dutch internet exchange operator NL-ix is acquiring Stockholm Internet eXchange (STHIX) from Swedish infrastructure provider Glesys, marking a significant step in its expansion across Northern Europe. The transaction will bring STHIX into NL-ix’s broader European network, creating new opportunities for businesses, internet service providers and digital platforms to access network interconnection services.
Announced on October 16, 2026, the acquisition gives NL-ix a stronger presence in Sweden while expanding the potential reach of its connectivity platform. Both companies expect customers to benefit from access to a wider range of networks and services as the integration progresses.
The companies have not disclosed the financial terms of the transaction. NL-ix says it will prioritize operational stability and continuity for existing STHIX customers before introducing broader services.
NL-ix Acquires STHIX to Strengthen Its European Network
The acquisition represents an important development in NL-ix’s strategy to expand its European internet interconnection business. By bringing STHIX into its network, the Dutch operator gains an established presence in the Swedish market and an opportunity to strengthen connections between networks operating across multiple European countries.
STHIX, short for Stockholm Internet eXchange, was founded in 2006. It provides carrier-neutral internet exchange services that allow participating networks to exchange internet traffic directly rather than relying exclusively on third-party transit providers.
According to the companies’ announcements, STHIX has approximately 84 connected networks and operates across multiple locations in Stockholm and other Swedish cities. Its infrastructure supports connection ports ranging from 100 megabits per second to 100 gigabits per second, serving networks with different capacity requirements.
For NL-ix, the acquisition provides an established platform from which to expand its Northern European operations. Instead of building an entirely new presence in Sweden, the company can build on STHIX’s existing infrastructure, customer relationships and local expertise.
The companies also plan to improve connectivity between their respective customer bases. Over time, STHIX customers are expected to gain access to NL-ix’s wider European interconnection services, while existing NL-ix customers will be able to use the STHIX network.
However, the immediate priority is maintaining reliable operations. The broader service expansion is expected to follow after the companies have ensured continuity for existing customers.
What the Acquisition Means for STHIX Customers
For organizations already connected to STHIX, the acquisition could eventually provide access to a broader range of connectivity options without requiring them to abandon their existing relationships with the Swedish exchange.
Internet exchanges play an important role in the modern digital economy. They enable internet service providers, content delivery networks, cloud platforms and other network operators to exchange traffic efficiently. By connecting to an exchange, participants can often improve routing efficiency, reduce dependence on external transit services and gain greater control over how traffic reaches its destination.
STHIX has established itself as a neutral exchange serving the Swedish market. Its local presence is an important part of its value, particularly for customers that need dependable connectivity within Sweden and across the wider Nordic region.
NL-ix has indicated that it intends to preserve this local presence and expertise. This commitment is significant because an acquisition involving network infrastructure can raise questions about service continuity, technical integration and the future availability of existing connections.
For now, customers should not expect an immediate overhaul of the platform. NL-ix has emphasized operational stability as its initial priority, with service expansion planned for a later stage.
Once the integration progresses, customers may benefit from access to additional interconnection products and a wider European network. The exact timing, product availability and commercial arrangements have not yet been detailed publicly.
Nevertheless, the transaction creates a potential pathway for STHIX customers to expand their network reach while continuing to use an established Swedish internet exchange.
Why Sweden Matters to NL-ix’s Expansion Strategy
Sweden is an important market for digital infrastructure in Northern Europe. Businesses, cloud service providers, telecommunications companies and digital platforms depend on reliable networks to support applications, online services and the movement of data between locations.
As digital services become more interconnected, organizations increasingly need network infrastructure that can support traffic across national borders. Internet exchanges help meet this demand by allowing networks to connect directly and exchange traffic more efficiently.
Through the STHIX acquisition, NL-ix gains an established position in Sweden and an opportunity to strengthen connectivity between Nordic networks and its broader European platform.
The move also gives NL-ix a foundation for developing additional services in a market where local network relationships and infrastructure expertise can be important competitive advantages.
Building a new internet exchange presence from scratch can require substantial investment in infrastructure, technical operations, customer acquisition and industry relationships. Acquiring an existing exchange offers another route to expansion, allowing the buyer to build on an established operation.
However, successful integration requires more than simply transferring ownership. Network operators must maintain service reliability, coordinate technical systems and ensure that customers understand any changes affecting their connections.
NL-ix’s stated emphasis on continuity suggests that the company intends to approach the transition in stages rather than immediately introducing widespread operational changes.
NL-ix’s Broader European Connectivity Ambitions
NL-ix was founded in 2001 as an alternative to Amsterdam’s AMS-IX. Since 2011, it has been owned by Dutch telecommunications group KPN, while operating as an independent company.
Over time, NL-ix has developed beyond traditional public internet peering. Its broader interconnection offering enables businesses to establish direct, monitored connections to approximately 2,400 public networks, including major cloud platforms such as Amazon Web Services, Microsoft Azure and Google Cloud.
These connections are increasingly important for companies that rely on cloud computing, distributed applications and digital services operating across multiple regions.
Direct interconnection can provide organizations with greater control over network traffic and help them manage connectivity requirements across different providers and destinations. The precise benefits depend on network architecture, traffic patterns, service agreements and the locations involved.
The STHIX acquisition fits into this wider strategy by extending the potential reach of NL-ix’s existing platform into Sweden.
Rather than treating each national market as a separate operation, a broader interconnection network can create opportunities to connect customers across multiple locations through a more unified service offering.
For customers, this could simplify the process of expanding connectivity into new markets. For NL-ix, it provides another opportunity to strengthen its position in the European network services sector.
The acquisition also follows NL-ix’s previously announced partnership with Anapaya, which focused on bringing SCION-based connectivity to Europe. SCION is a network architecture designed to provide greater control over network paths and support secure communication between participating networks.
Although the STHIX transaction and the Anapaya partnership address different aspects of connectivity, both reflect NL-ix’s broader interest in expanding its network services and infrastructure capabilities.
Glesys Shifts Its Focus Toward Core Infrastructure
The sale also reflects Glesys’s strategic priorities.
Glesys acquired STHIX in 2020 and subsequently developed the exchange as part of its wider Nordic digital infrastructure business. The company provides infrastructure-as-a-service offerings and operates in areas including cloud services and data centers.
By selling STHIX to NL-ix, Glesys can concentrate more closely on these core activities while maintaining a relationship with the exchange.
Glesys has indicated that it will remain connected to STHIX as a customer and infrastructure partner. This arrangement is intended to support continuity while allowing the exchange to become part of NL-ix’s wider European network.
For Glesys, the transaction represents a shift in focus rather than a complete withdrawal from the digital infrastructure ecosystem. The company can continue developing its principal services while its former exchange business gains access to a larger interconnection platform.
The arrangement also illustrates how infrastructure providers can choose to specialize in different parts of the digital supply chain. Some companies concentrate on cloud computing, hosting and data center operations, while others focus on connecting networks and facilitating the exchange of traffic.
These activities remain closely related, but they require different commercial strategies and operational priorities.
With STHIX moving to NL-ix, Glesys can concentrate on its core infrastructure business while continuing to support the exchange through its ongoing relationship.
What Internet Exchange Infrastructure Means for Businesses
The significance of the acquisition extends beyond the two companies involved. Internet exchanges form part of the underlying infrastructure that supports everyday online activity, from video streaming and cloud applications to enterprise software and international communications.
When networks exchange traffic directly, they can reduce the number of intermediaries involved in delivering data. Depending on the circumstances, this can improve routing efficiency, reduce latency and give participating organizations greater flexibility in managing their connectivity.
For businesses, reliable interconnection can be particularly important when applications depend on frequent communication between cloud environments, data centers, customers and business partners.
A company operating across several countries may need connectivity to multiple internet service providers, cloud platforms and content networks. An exchange or interconnection platform can help bring those connections together and simplify network management.
However, an internet exchange does not automatically guarantee better performance for every customer. Results depend on the networks involved, the physical locations of connections, available capacity, routing arrangements and the quality of the underlying infrastructure.
The value of an expanded network therefore depends on how effectively the operator integrates its infrastructure and makes useful connections available to customers.
For NL-ix, the STHIX acquisition creates an opportunity to connect an established Swedish exchange with a broader European network. If the integration delivers on its stated goals, customers could gain more options for reaching networks and services across national borders.
The transition will need to preserve the reliability and neutrality that customers expect from an internet exchange while supporting the development of additional services.
Integration and Service Continuity Remain Key Priorities
Despite the strategic opportunities, the acquisition also brings practical challenges.
Network infrastructure must operate reliably during changes in ownership, management and technical integration. Even small disruptions can affect customers that depend on stable connectivity for business-critical applications.
NL-ix has stated that operational stability and continuity will come first. This means the company intends to maintain existing operations before expanding the service portfolio.
That approach may help reduce uncertainty for STHIX customers during the transition. It also provides time for the companies to assess how their networks, commercial arrangements and support processes can work together.
Several details remain unclear. The companies have not announced the acquisition price, provided a detailed integration timetable or outlined exactly which additional services will become available to STHIX customers.
Customers and industry observers will therefore need to watch for further announcements to understand how the transaction will affect connectivity options, pricing and service delivery over time.
The long-term outcome will depend on how effectively NL-ix combines STHIX’s local presence with its existing European capabilities.
What Happens Next for NL-ix and STHIX?
The immediate focus is expected to remain on maintaining the existing exchange and ensuring a smooth transition for customers.
As integration progresses, NL-ix plans to broaden the opportunities available to STHIX customers and make the Swedish network accessible to its existing customer base. This reciprocal access could create new routes for organizations seeking connectivity across Northern Europe and other European markets.
The acquisition also strengthens NL-ix’s ability to build on an existing network rather than relying solely on organic expansion. Whether that translates into a substantial increase in customer adoption or new service offerings will depend on the company’s execution and the needs of its customers.
For Glesys, the sale creates a clearer focus on cloud services, data centers and Nordic digital infrastructure while preserving its relationship with STHIX.
For the wider industry, the transaction highlights the continuing importance of network interconnection as businesses and digital platforms operate across increasingly connected markets.
Ultimately, the acquisition is a strategic step toward a more integrated European connectivity platform. Its immediate impact may be limited as operations remain stable, but the longer-term opportunity lies in expanding network access, improving service choice and connecting more organizations across national borders.
The next phase will show how NL-ix turns that opportunity into practical benefits for customers in Sweden and throughout Europe.
