Summary
- NL-ix completed its acquisition of Stockholm Internet eXchange (STHIX) from Glesys on 16 October; financial terms were not disclosed.
- STHIX, founded in 2006 and previously acquired by Glesys in 2020, will become part of NL-ix's distributed European interconnection platform.
- Glesys remains a customer and infrastructure partner, while service continuity takes priority over future network and product integration.
Dutch interconnection operator NL-ix has acquired Stockholm Internet eXchange (STHIX) from Swedish digital infrastructure provider Glesys, extending its European network into the Swedish internet exchange market.
The completed transaction was announced by both companies on 16 October. It places STHIX within NL-ix’s wider interconnection platform, while Glesys will remain a customer and infrastructure partner supporting the exchange’s operations.
The companies have not disclosed the acquisition price, transaction valuation or associated investment commitments.
STHIX was founded in 2006 as a carrier-neutral internet exchange serving network operators, internet service providers, cloud companies, content networks and other organisations exchanging traffic in Sweden.
Glesys acquired the business in 2020, with the intention of supporting open and reliable interconnection infrastructure. The latest transaction transfers ownership to an operator specialising in internet exchange and connectivity services across multiple European markets.
NL-ix is a wholly owned subsidiary of Dutch telecommunications company KPN. Its acquisition of STHIX expands the geographic scope of its network and provides an established Swedish operation from which to develop additional connectivity services.
Existing services remain the immediate priority
NL-ix says its first priority is maintaining the operational stability and continuity of STHIX’s existing services.
The buyer intends to preserve the Swedish exchange’s local presence and technical expertise. Additional products and access to the wider NL-ix network are planned over time, rather than being presented as services already fully integrated across every existing connection.
An internet exchange allows participating networks to exchange traffic directly through shared interconnection infrastructure. These arrangements can reduce dependence on third-party transit services where networks establish suitable peering relationships.
The underlying equipment typically includes switching systems, network interfaces and fibre connections serving participating networks. Each organisation determines the traffic it exchanges through the arrangements available at the exchange.
Direct interconnection can provide alternative routing options and reduce the distance travelled by some traffic, but the resulting performance depends on network configuration, participating networks and commercial arrangements.
Ownership of an internet exchange does not automatically establish lower latency, greater resilience or cheaper connectivity for every customer. Those outcomes require technical and commercial changes whose effects can be measured after deployment.
NL-ix’s announcement identifies wider European reach and a broader product portfolio as intended benefits. It does not provide measurements demonstrating that STHIX traffic is already travelling over new routes or that existing customers have experienced an improvement in performance.
The buyer also intends to make the Swedish exchange network available to its existing customer base. That could provide additional opportunities for European networks seeking to establish interconnection in Sweden, although the company has not published an implementation timetable for individual services.
No updated traffic statistics, customer totals or technical capacity figures were included in the acquisition announcements. The number of connections or amount of traffic added to NL-ix’s platform therefore cannot be independently quantified from the transaction statements.
Glesys retains an infrastructure role
Glesys says the sale supports its strategy of concentrating investment and management resources on Nordic cloud services, data centres and digital infrastructure.
The company provides cloud infrastructure, colocation, dedicated servers and network services across the region. Selling STHIX does not mean those other operations have been transferred to NL-ix.
Glesys will continue to act as both a customer and infrastructure partner. The arrangement preserves a relationship with the exchange while transferring responsibility for its ownership and wider strategic development.
Glenn Johansson, chief executive of Glesys, said the original 2020 acquisition had been intended to support an open and well-connected Swedish internet ecosystem. The company now considers NL-ix better positioned to develop STHIX within a larger specialist interconnection business.
The seller’s continuing involvement is relevant because an exchange operator does not necessarily own every facility, network route or supporting service used by its platform.
Interconnection businesses can operate through equipment located in third-party data centres and through connectivity supplied by separate infrastructure companies. Their physical presence and service availability depend on those underlying arrangements.
Neither announcement establishes that NL-ix has acquired Glesys’s data centre buildings, wider cloud platform or Nordic colocation business. The identified transaction concerns Stockholm Internet eXchange.
DataCentral previously reported on Glesys’s separate data centre development plans in Oulu, Finland. That project is outside the scope of the STHIX transaction and remains an example of the infrastructure activities on which the company intends to concentrate.
European network integration will follow
NL-ix describes the acquisition as part of its strategy to expand interconnection opportunities across Europe, with particular emphasis on Northern Europe.
The transaction provides an established Swedish operation rather than requiring the buyer to create an entirely new exchange from the beginning. However, the companies have not disclosed whether additional switching equipment, fibre capacity or physical interconnection locations will be required.
Any subsequent integration will need to preserve existing customer services while introducing new technical and commercial options. Changes to the available network paths may also require participating organisations to review their own routing and interconnection arrangements.
For customers, the distinction between a completed ownership transfer and future service integration is central. Existing connectivity is intended to continue, while access to additional European network services remains part of the announced development programme.
NL-ix has not specified the timetable for completing those changes or provided a forecast of revenue, traffic growth or customer additions attributable to STHIX.
The confirmed development is therefore the completed acquisition and the continuing infrastructure partnership with Glesys. Further technical announcements will be required to establish how the transaction changes the exchange’s practical connectivity offerings.
