COLO-1 at NXDATA-1 became operational, marking the first carrier-neutral data center in Romania. This milestone laid the foundations for an open colocation and interconnection ecosystem that continues to develop today.

In 2004, NXDATA completed the expansion of the data center with the opening of COLO-2, adding another 50 m² of colocation space. In the same year, Romtelecom installed the first SDH equipment at the NXDATA neutral colocation center, while Vodafone, Orange, Cosmote and RCS-RDS included NXDATA in their reference offerings for interconnection with their own voice networks. The increase in the number of customers also led to an expansion of the cooling capacity of the NXDATA-1 data center.

In 2006, NXDATA-1 colocation space reached 200 m², while cooling capacity and electrical infrastructure were expanded. That same year, NXDATA implemented the first VESDA system in a commercial data center in Romania and introduced dedicated cable trays for fiber-optic cable management.

In 2008, NXDATA began construction of the company's second data center, NXDATA-2, representing an investment of more than EUR 1 million. Completed by the end of the year, the new data center was designed with redundant infrastructure and connected to NXDATA-1 through a dedicated fiber-optic network, strengthening the company's interconnection ecosystem. In parallel, NXDATA continued modernizing and expanding the NXDATA-1 infrastructure to support the continued growth of colocation and connectivity services.

In 2010, NXDATA completed the connection of the NXDATA-1 and NXDATA-2 data centers to the Netcity metropolitan network, strengthening access to Bucharest's fiber-optic infrastructure. That same year, the backup power capacity of NXDATA-2 was expanded through the installation of new diesel generators, while TELECOMUNICAȚII CFR chose NXDATA to establish a Point of Presence within the NXDATA-2 data center.

In 2012, NXDATA continued expanding its infrastructure by developing a new colocation room, COLO-4, at NXDATA-1, along with further investments in the cooling systems of the NXDATA-1 and NXDATA-2 data centers. That same year, information about the two data centers was included in the global TeleGeography database.

In 2014, NXDATA was one of the sponsors of RONOG #4, the first Network Operators Group conference organized in Romania, held immediately after the EURO-IX Forum. Participation in this event reflected the company's active involvement in the development of the telecommunications operator community and the interconnection ecosystem in Romania.

In 2016, NXDATA completed another modernization program for the power supply infrastructure at the NXDATA-1 data center. The existing diesel generators were replaced with two new units, each with a capacity of 1,500 kVA, tested at nominal power using specialized load-bank equipment. The investment strengthened the resilience of the infrastructure and prepared the data center for increasingly demanding availability and operational continuity requirements.

In 2018, specialists from the NXDATA team obtained the international Uptime Institute Accredited Operations Specialist (AOS) and Accredited Tier Designer (ATD) certifications, confirming the company's expertise in designing and operating critical infrastructure. That same year, the NXDATA interconnection ecosystem expanded through the launch of the TVX Platform, a neutral national infrastructure administered by the InterLAN Association that facilitates TV content distribution via IP Multicast to cable operators and Internet service providers.

In 2020, NXDATA continued developing its infrastructure by starting construction of the new COLO-8 colocation room at the NXDATA-1 data center. That same year, the launch of the Amazon CloudFront Edge Location in Bucharest and the growing presence of international network and content distribution providers contributed to the development of the NXDATA interconnection ecosystem and reduced latency for users.

In 2022, NXDATA completed construction and brought the new COLO-8 colocation room into operation, expanding the capacity of the NXDATA-1 data center. That same year, site preparation works began for the development of NXDATA-3. The project represents the largest investment in the company's history and marks the next stage in the expansion of the critical infrastructure and interconnection ecosystem developed by NXDATA.

In 2024, the NXDATA-3 project continued to advance through the technical and operational stages required for the development of the new data center. Designed for IT infrastructure with high power, availability and scalability requirements, NXDATA-3 represents the next stage in the expansion of NXDATA's capacity.

In 2026, Zayo Europe selected NXDATA-1 to launch its first Point of Presence in Bucharest, providing direct access to one of the world's most extensive Tier 1 IP networks and strengthening NXDATA's role as a regional interconnection hub. In parallel, development of NXDATA-3, the company's third data center and the largest expansion project in NXDATA's history, continues.
