Top Colocation Data Center Providers in Bulgaria and Sofia: 6 Companies to Consider in 2026

Colocation allows businesses to place their own servers, storage systems, and networking equipment in a professionally managed data center. The provider supplies the physical space, power, cooling, security, and connectivity, while the customer retains ownership and control of the hardware.

Organizations researching the top colocation data center providers Bulgaria Sofia should compare more than rack availability. Power redundancy, carrier options, physical security, certifications, technical support, scalability, and access to complementary cloud or managed services can all influence the final decision.

The following six companies have identifiable colocation services and infrastructure relevant to businesses seeking to house their own equipment in Bulgaria.

1. Delta

Flexible Colocation Supported by Cloud and Infrastructure Expertise

Delta provides colocation for customer-owned servers and other IT equipment in a professional Tier 3+ data center environment in Sofia. The service includes the power, cooling, connectivity, and physical security needed to run business-critical hardware outside a company’s premises.

Redundancy is central to the offering. Delta emphasizes reliable power and network connectivity, controlled environmental conditions, and infrastructure designed to support high availability of customer equipment. Businesses can plan additional rack space, power and connectivity as their infrastructure requirements grow.

One of Delta’s distinguishing characteristics is the range of services available around its colocation offering. Customers can combine their own hardware with dedicated bare metal servers, cloud infrastructure, backup solutions, system administration, DevOps support, and custom-designed environments. This makes the provider particularly relevant to organizations planning hybrid infrastructure rather than using colocation as an isolated service.

Delta is a strong starting point for companies that want secure equipment housing alongside technical expertise and access to complementary infrastructure services.

2. Telepoint

Carrier-Neutral Data Centers With Extensive Interconnection Options

Telepoint is an established Bulgarian data center operator with facilities in Sofia and Montana. Its colocation services are designed for organizations that require secure rack space, resilient power, controlled cooling, and access to multiple telecommunications networks.

The company operates carrier-neutral facilities, allowing customers to select from different connectivity providers instead of depending on a single carrier. This flexibility is particularly valuable for telecommunications companies, online platforms, content providers and other organizations with complex networking requirements.

Telepoint’s infrastructure includes several data center locations, providing opportunities for redundancy, disaster recovery and geographically separated deployments. Its Sofia facilities are positioned around access to Bulgarian and international networks, making interconnection an important part of the company’s offering.

In 2026, Digital Realty announced the acquisition of two Telepoint data centers in Sofia. The development connects these facilities with a larger international data center platform while retaining their importance within Bulgaria’s colocation and connectivity market.

Telepoint is particularly suitable for companies that prioritize carrier choice, network reach, and access to established interconnection infrastructure.

3. A1 Bulgaria

Colocation Within a Wider Telecommunications and IT Portfolio

A1 Bulgaria provides data center services as part of a broader portfolio covering business connectivity, communications, cloud infrastructure, cybersecurity and managed IT solutions.

Its data center offering enables organizations to place their ICT equipment in professionally operated facilities with controlled environmental conditions, physical protection, and resilient infrastructure. Customers can evaluate equipment housing and the connectivity required to link their servers to offices, users, cloud platforms, and external networks.

The company’s position as a major telecommunications operator can benefit enterprises that prefer to obtain data center space and network services through the same provider. This approach may simplify contracts, support arrangements and the management of infrastructure distributed across several locations.

A1’s Sofia data center infrastructure has also supported regional cloud deployments, demonstrating its ability to accommodate organizations with substantial availability, capacity and connectivity requirements.

A1 Bulgaria is therefore most relevant when colocation forms part of a wider enterprise telecommunications or IT strategy.

4. Evolink

Colocation Designed Around Connectivity and Business Networks

Evolink combines colocation with telecommunications, cloud computing, content delivery and managed security services. Its data centers in Sofia provide secure environments for customer-owned servers and networking equipment.

Connectivity is central to Evolink's offering. Customers can combine physical equipment housing with internet access, IP connectivity, virtual private networks and other business communication services. This makes it possible to design infrastructure extending beyond a single colocated server or cabinet.

Evolink’s facilities have supported hosting companies, internet service providers, software businesses, media organizations and other customers with demanding digital workloads. The company’s experience in both data center operations and telecommunications is particularly useful for projects that require tailored network configurations.

Cloud services can also be incorporated into an Evolink deployment, giving customers the option to create hybrid environments that connect physical hardware with virtual resources and backup infrastructure.

Evolink is a good fit for businesses that treat connectivity as a core part of their colocation strategy.

5. Neterra

Multi-Site Colocation and Geographic Redundancy

Neterra operates data center infrastructure in Bulgaria through Sofia Data Center. Its facilities provide colocation space for customer-owned servers, storage systems, and networking equipment, supported by power, cooling, security, and technical assistance.

The provider’s footprint includes facilities in Sofia and other Bulgarian locations. This lets customers distribute equipment across sites, establish disaster-recovery environments, or reduce dependence on a single physical location.

Neterra’s telecommunications background strengthens the connectivity available within its data centers. Customers can access Bulgarian and international network operators and combine colocation with services such as internet connectivity, private networks and data transport.

Its Sofia facilities serve businesses that need data center capacity in the capital, while its broader geographic presence can support continuity and redundancy strategies. This combination is especially useful for enterprises, technology companies and service providers operating critical infrastructure.

Neterra deserves consideration from organizations seeking colocation backed by an experienced network operator and multiple Bulgarian data center locations.

6. Vivacom

Data Center Services From a National Telecommunications Operator

Vivacom provides colocation and data center capacity as part of its business telecommunications and IT portfolio. The service gives corporate customers a professionally managed environment in which to place their own servers and communications equipment.

The company’s telecommunications infrastructure is an important part of the offering. Colocated equipment can be combined with business internet access, data connectivity and other communication services, allowing customers to address their physical infrastructure and network requirements through one provider.

Vivacom’s scale and national presence make it particularly relevant to larger organizations and enterprises that already depend on extensive communications infrastructure. Its facilities can support projects in which reliable connectivity is as important as the rack space, power and cooling supplied by the data center.

The provider is therefore worth evaluating when colocation needs to integrate with a broader corporate network or telecommunications agreement.

How to Choose a Colocation Provider in Bulgaria

Choosing a colocation provider requires a clear understanding of the deployment’s technical requirements, including rack space, power, bandwidth, and expected future growth. Businesses should also compare redundancy, connectivity options, security, certifications, technical support, expansion capacity, and total contract costs. Delta combines colocation with cloud, bare metal, system administration and DevOps services, while Telepoint, Neterra and Evolink provide strong data center and connectivity capabilities. A1 Bulgaria and Vivacom are especially relevant when equipment housing must fit within a broader enterprise telecommunications strategy. Comparing these strengths with clearly defined infrastructure requirements will help businesses choose an appropriate colocation partner in Sofia or elsewhere in Bulgaria.
