Overview

CE Colo is a Czech data center operator and brand that provides carrier-neutral colocation and interconnection services from its facility in Prague. According to its own materials, it positions itself as a leading provider of state-of-the-art carrier-neutral data center services in Central Europe, offering secure and connected environments where customers connect, house and distribute mission-critical data, web content and media. The company was established through the acquisition of Sitel Data Center (SDC) by the GTS group in January 2011, and it states that it is now part of the global DTAG (Deutsche Telekom AG) group. The core of the business is colocation. CE Colo offers solutions across a range of sizes, from a rack or part of a rack in a shared area for entry-level requirements, up to a cage or a dedicated customer room for larger deployments. Its published service descriptions cover rack cabinets of 42U to 47U, cages that add an extra layer of physical security (with biometric fingerprint entry possible), and private rooms with their own fire safety zone, dedicated PDU and CRAC units. Customers are given 24/7/365 physical access to their equipment, and a Remote Hands service allows basic tasks to be carried out remotely within the customer's own space. Networking and interconnection are central to the CE Colo proposition. The company says it is constantly expanding its large telco/carrier availability on-site, giving customers more options when ordering services. It notes that the most important peering points within the Central European region are hosted at or reachable from its facility, which can save customers money on IP transit, and that local exchanges such as NIX.CZ and Peering.cz are available. Its homepage cites figures of 2.6 MW of DC power, 3,400 m² of customer space, 18.8k fibers and 6.1k copper connections. CE Colo emphasizes the quality of its critical infrastructure, focusing on uninterruptible power, cooling and complex security. It holds internationally recognized ISO certifications, including ISO 9001:2015 for quality management, ISO 14001:2015 for environmental management and ISO 27001:2022 for information security management, as well as an EKO Gold Green Power Usage Certificate. The company operates a 24/7 help desk and presents itself as a long-term, reliable partner for businesses that need to grow their data center infrastructure in the Czech and wider Central European market.

History

CE Colo traces its origin to the acquisition of Sitel Data Center (SDC) by the GTS group in January 2011. That transaction created the CE Colo brand and business, which took over and continued to operate the data center facility in Prague. From the outset, the company focused on carrier-neutral colocation and interconnection, positioning its Prague site as a key interconnection point for the Internet in the Czech Republic and the wider Central European region. After its establishment, CE Colo continued to develop the facility and its service portfolio. Its own account describes a long-term tradition and a focus on providing customers with the data center infrastructure needed to grow their businesses. The company expanded its colocation options to cover the full range of customer requirements, from a rack or part of a rack in a shared area, through cages, to dedicated private rooms with their own fire safety zone, dedicated PDU and CRAC units. It also built out networking capabilities, maintaining and expanding a large on-site telco/carrier presence and ensuring that major regional peering points such as NIX.CZ and Peering.cz are available or reachable. CE Colo states that it is now part of the global DTAG (Deutsche Telekom AG) group, reflecting the consolidation of the GTS group's assets within Deutsche Telekom. The company has invested in a brand new site to provide enough capacity for customer requirements, and its homepage cites operational figures including 2.6 MW of DC power, 3,400 m² of customer space, 18.8k fibers and 6.1k copper connections. It has also obtained internationally recognized certifications — ISO 9001:2015, ISO 14001:2015 and ISO 27001:2022 — as well as an EKO Gold Green Power Usage Certificate, underlining its emphasis on quality, environmental management and information security. Today CE Colo operates as a Czech data center provider serving customers who need secure, connected environments for mission-critical data, web content and media.
