📄 Editorial Review

🔃 Bytesnet is part of Eurofiber Group
(3*) 🔧 Services: Data Center Own datacenter
Bytesnet is a Dutch data center and IT infrastructure provider that focuses on colocation, cloud computing, high performance computing (HPC), and connectivity rather than classic shared hosting. The company’s roots go back to the late 1990s with the Groningen and Rotterdam Internet Exchanges (GN-IX and R-IX / nl-ix.net ), and since 2008 they have operated under the Bytesnet name as a fully-fledged data center operator with their own facilities in Rotterdam and Groningen. The datacenter operations have been acquired by Eurofiber, and now sit within a larger open-access digital infrastructure group, but Bytesnet continues to operate its services with the same regional focus and identity.

The portfolio is built around two Tier III data centers: Datacenter Rotterdam in the "Spanish Cube" (Spaanse Kubus) and d’ROOT in Groningen. Both are clearly aimed at organizations that treat IT as critical infrastructure: healthcare institutions, universities, research labs, government bodies, and enterprise customers. The emphasis is on business continuity, security, and sustainability rather than mass-market web hosting.

Colocation is the foundation of the offer. Bytesnet provides standard rackspace, private corridors & suites, and twinning solutions where systems are mirrored to a second site for redundancy. Customers can bring their own hardware and run it in a highly conditioned environment, while relying on SmartHands engineers for on-site tasks such as installations, checks, and troubleshooting. For organizations that prefer strong physical control over their servers, but do not want to build and run their own data center, this model is very attractive.

On top of colocation, Bytesnet operates a cloud computing platform delivered as Infrastructure-as-a-Service (IaaS) and private cloud. Customers can run virtual machines in Dutch data centers, scale vCPU, RAM, and storage, and build high-availability setups with geographically separate backups. Cloud resources are offered as a monthly subscription or pay-per-use, with a self-service portal (for sizing and provisioning) being rolled out. Security options such as firewalls, DDoS mitigation and ransomware protection are integrated into this environment, and there is support for hybrid deployments that link on-premise systems with Bytesnet’s private cloud and major public cloud platforms like Azure, Google Cloud, and AWS through a Cloud eXchange fabric.

A distinctive part of the portfolio is High Performance Computing (HPC). Bytesnet runs a shared HPC supercomputing environment in its data competence centers, with aggregated CPU, GPU, storage and FPGA resources designed for workloads such as AI, machine learning, simulation, digital twins, medical imaging and big data analytics. Customers can shift from CAPEX to HPC-as-a-service, paying only for the capacity they consume while still running their workloads within Dutch facilities under Dutch law. The HPC infrastructure is cooled using immersion technology and integrated into a district heating network so that residual heat is reused to warm buildings in Groningen, which underlines the sustainability angle.

Finally, connectivity is treated as a separate service line, not just an add-on. Bytesnet operates carrier-neutral data centers and offers a range of network services: cross connects within the facilities, links to multiple carriers, dark fiber with Wavelength Division Multiplexing for high-capacity private links, and cloud connectivity for access to public cloud platforms. The design aims at secure, redundant connections where traffic can be switched between providers if one has an outage. For customers, that means they can combine colocation, cloud and HPC under one roof while still choosing their preferred network carriers and cloud partners.

Overall, Bytesnet is a regional, engineering-driven provider for organizations that value local presence, strict Dutch jurisdiction, sustainability, and direct access to technical staff more than low-cost, off-the-shelf shared hosting plans.

💰 Price & Cost

Bytesnet does not operate as a classic "web host" with a public price list for shared hosting or VPS. Instead, services are tailored for organizations and sold on a consultative, contract-based basis.

For cloud computing, there are two commercial models: monthly subscription for a fixed cloud environment and pay-per-use for more elastic setups where vCPUs, RAM and storage can be scaled according to load. The virtual server capacity and storage services are framed so that customers can predict monthly costs while still adjusting resources when needed. Pricing details, however, are only available via request forms or direct contact, so there is no transparent price grid for quick comparison.

The HPC platform is sold as HPC-as-a-service, explicitly positioned as an OPEX alternative to buying supercomputing hardware. Customers pay based on actual usage of computing and storage capacity. This model is meant to make advanced computing more accessible to research institutes, healthcare, and data-heavy industries without major up-front investment.

For colocation (rackspace, private suites, twinning) and connectivity (dark fiber, cloud exchange, carrier links), there are no listed prices; everything is quotation-based. This reflects the enterprise-style orientation: costs depend on rack counts, power densities, bandwidth, redundancy requirements, and service levels.

Billing is effectively tailored, and although it is natural to expect contracts to be denominated in euro for a Netherlands-based provider, explicit multi-currency options are not promoted.

🏢 Data Center

Bytesnet operates two key Tier III data centers:

• Datacenter Rotterdam – located in the Spanish Cube (Spaanse Kubus) on the northern edge of Rotterdam. It grew out of the Rotterdam Internet Exchange (R-IX) and still serves large customers in healthcare and education, including major hospitals and institutions. Power, cooling and connectivity are fully redundant, with a guaranteed uptime of 99.982%. The facility is directly connected to the European internet backbone and offers 24/7 physical access for authorized customer staff, backed by on-site Bytesnet engineers. Sustainability is woven into the design, including free-cooling strategies and continuous optimization of power usage; this location has previously been recognized for energy efficiency in the European data center landscape.
• Datacenter Groningen – d’ROOT – positioned on Campus Groningen, this is a state-of-the-art facility and data lab that combines an advanced data center with an innovation hub for universities, research institutes and businesses. It is powered entirely by green energy and uses Immersed Computing to cool HPC hardware by submerging systems in a special cooling fluid. Residual heat is captured and supplied to the local heating company to warm buildings, making it one of the more sustainable data centers in Europe. As with Rotterdam, infrastructure is built to Tier III standards with multiple power feeds, redundant emergency power, and strict environmental control.

Both sites focus heavily on security and continuity: multi-layer access control with badge plus biometrics, SmartAccess for rack-level authorization, advanced fire prevention and detection systems, and tight control of humidity, dust and temperature to extend hardware lifespan. Data remains physically within the Netherlands and therefore under Dutch and EU regulation, which is a strong point for healthcare, government, and research customers who want to avoid data leaving the country.

Bytesnet holds a broad set of certifications, including ISO 9001 (quality), ISO 14001 (environment), ISO 27001 (information security), ISO 27701 (privacy) – where they were among the first Dutch data centers – ISAE 3402 Type II, and NEN 7510 for healthcare-related information security. These attest to structured processes, audited controls, and a consistent focus on compliance.

From an uptime and reliability perspective, the combination of Tier III design, 99.982% availability commitment, redundant connectivity, and mirrored/twin site options places Bytesnet firmly in the serious data center category, rather than in commodity hosting.

✍️ Customer Support

Customer interaction is intentionally personal and local. Instead of call centers in multiple countries, Bytesnet emphasizes direct contact with staff in Rotterdam and Groningen. Phone numbers for both locations are prominently published, and the messaging is that when customers call, they speak to someone who knows the environment and can help without navigating complex menus.

For colocation customers, support extends into the data halls through SmartHands: certified engineers who can perform physical tasks on equipment, check cables, change components, or handle scheduled interventions. This allows customers’ own IT teams to stay remote while still maintaining tight operational control.
In the cloud and HPC context, support runs from initial architecture and design (e.g., how to set up an IaaS environment, how to structure HPC workloads) through to ongoing monitoring and capacity planning. There is a clear emphasis on advisory support for hybrid setups, HPC workloads, and data analytics tooling, not just fixing tickets.

The company presents itself as accessible, nearby, and cooperative, focusing on building long-term relationships with IT teams, researchers, and technical stakeholders. For organizations that value close contact with an engineering-led team instead of a fully self-service, anonymous platform, this is a strong differentiator.

🔨 Control Panel

Bytesnet does not use consumer hosting panels, because the service stack is different from traditional shared hosting.
For cloud computing, they are rolling out a self-service portal where customers can size and adjust their cloud resources – number of vCPUs, RAM, storage – and have instances available within minutes. This interface is meant to provide the agility of public cloud while keeping data and infrastructure in Dutch facilities. Administration and deeper configuration are usually handled in cooperation with Bytesnet’s team or the customer’s own IT department, rather than through a generic web hosting GUI.

In HPC, management options range from bare metal access for advanced teams to more managed environments, including virtual desktops or turnkey analytical environments. Here, the "control panel" is more about HPC job management, resource allocation and integration with data analytics tools than about hosting websites.

For colocation, the primary "control" is physical and contractual: customers manage their own hardware and operating systems, with Bytesnet providing environmental monitoring, access control (including SmartAccess logs for who entered which rack and when), and network connectivity. Any remote operations are typically executed via SmartHands rather than through a traditional control panel.

In practice, Bytesnet is closer to an enterprise IT infrastructure provider than a web host in the traditional sense, and its management tooling reflects that.

🎯 Conclusion

Bytesnet is an good choice for organizations that need serious infrastructure on Dutch soil rather than low-cost web hosting. The combination of Tier III data centers, comprehensive colocation services, IaaS and private cloud, and a mature HPC platform makes it particularly appealing to:

• healthcare providers handling sensitive patient data,
• universities and research institutes running data-intensive workloads,
• public sector bodies that prefer to keep data physically in the Netherlands,
• enterprises looking for regional, carrier-neutral data center capacity with strong sustainability credentials.

Strengths include the long-standing roots in GN-IX and R-IX, the dual-site setup in Rotterdam and Groningen, a very strong stance on sustainability and energy innovation, and a broad set of certifications that match strict compliance requirements. The acquisition of Bytesnet’s data centers by Eurofiber further embeds the facilities into a larger European infrastructure ecosystem, which can be reassuring for customers planning long-term.

On the downside, Bytesnet is not designed for small website owners who want a quick shared hosting plan with a ready-made control panel and transparent low pricing. Pricing is custom, money-back guarantees are not part of the public offering, and customers should be ready to engage in a more involved sales and design process. For many mid-sized businesses, researchers, and institutions, that is precisely the point: the service feels more like working with a data center partner than with a commodity host.

Bytesnet website is supporting English and Dutch languages.

For future hosting customers who need colocation, private cloud, or HPC in the Netherlands and who value local presence, compliance, and sustainability, Bytesnet is a solid candidate to consider in the short list.
