Colt DCS Brand Guidelines: Colt’s Data Centres, a 2021 AtlasEdge Sale & Hyperscale Campuses

A London telecoms network and its first data centres.

Colt Data Centre Services, known as Colt DCS, grew out of the London telecoms company Colt. English Wikipedia says Colt was founded in 1992 as City Of London Telecommunications by James Hynes, with money from Fidelity Investments. It began by building a telecoms network in London, won a licence in 1993 to compete with British Telecom and Cable and Wireless in voice and data, listed on the London Stock Exchange in 1996 and spent the following decade building networks in major European cities. The Colt name is an acronym of that first company name, and it is unrelated to the American firearms brand.

Data centres arrived early in that story. Colt DCS says its first data centres were built in 1999 and that its hyperscale operations began in 2016. The wider group changed shape around the same period: in November 2014 Colt acquired the Japanese telecoms company KVH, which Wikipedia says helped it expand in Asia, and in August 2015 Fidelity took full ownership, ending Colt’s time as a listed company.

The data-centre arm now operates as a company of its own. The UK register at Companies House shows Colt Data Centre Services UK Limited incorporated in July 2010, and the company’s website is published under the name Colt Data Centre Services Holdings. Colt DCS describes itself as a subsidiary of Colt Group Holdings Limited. The network business continues separately as Colt Technology Services, which keeps the original Colt branding on its own website.

From city colocation to hyperscale campuses.

The turn towards very large cloud customers became public in 2021. On 2 November that year Capacity reported that AtlasEdge, a joint venture formed earlier that year by Liberty Global and Digital Colony, had acquired 12 data centres from Colt DCS for an undisclosed sum, with Colt Technology Services staying on as an anchor tenant in several of them. Capacity described the deal as a spin-off that would let Colt DCS concentrate on its hyperscale portfolio, and quoted the then chief executive saying the company was restructuring around its hyperscale facilities.

Today the company says it runs 15 operational data centres, with 12 further sites under development, across nine cities in the UK, France, Germany, the Netherlands, India and Japan. Its operating sites sit in and around London, Frankfurt, Paris, Rotterdam, Mumbai, Osaka and Tokyo, including the Osaka Keihanna site in the Kansai region, where the Inzai campus in Chiba New Town, about forty minutes from central Tokyo, holds four buildings, the company says.

Colt DCS describes its sites in megawatts of IT power. By its own figures, Tokyo Shiohama, in Koto-ku, offers 5.6MW; Inzai 1 offers 8MW; and London North, at Welwyn Garden City, offers 35MW. The company says London North was first designed for large enterprises and financial institutions and has since been developed for cloud service providers, and that the second phase of its Mumbai site will deliver 134MW on a site of 62,490 square metres. The first building of its Hayes campus in west London, London 4, is planned at 31MW across five floors, and the company says that phase was fully let before completion. In August 2026 it said it had nearly 800MW of capacity under development; elsewhere on its website it sets out a plan to take ten owned sites from 190MW to one gigawatt over ten years.

Partnerships carry much of the expansion in Asia. Colt DCS lists three joint ventures there: a 2021 agreement between Devonshire Investors and the trading house Mitsui & Co for hyperscale data centres in Japan; a 2024 venture with the Indian real-estate group RMZ covering Mumbai and Chennai; and a 2025 venture with ESR, an Asia-Pacific real-estate manager, for a 130MW hyperscale campus in Minoh City, Osaka. In Europe its development list adds new buildings in Frankfurt, London and Paris, and land about ten kilometres east of Berlin for two data centres planned at a combined 54MW.

How data-centre operators present themselves.

Data-centre operators sell something most of their customers never see in person: buildings full of power, cooling and racks, usually in business parks on the edge of a city. Their websites and reports therefore do much of the work of explaining what they own and where it is. In this guide’s set, the companies present themselves through a small number of recurring formats rather than a consumer product.

The first is the campus itself. Operators publish aerial photographs and architectural renderings of their sites, often before a building is finished, together with galleries and short videos. These images are the company’s own material and show the buildings as the operator wants them seen; a rendering of a planned campus is a plan, not a finished site.

The second is the map and the number. Location pages are organised by city or region, and some show a stylised map of how sites relate to one another, sometimes marked as not to scale. Capacity is given in megawatts and floor area in square metres, alongside counts of sites in operation and under construction. Founding years, listing dates and lists of markets often appear as a strip of figures on a home page.

The third is the technical and corporate layer. Interconnection pages describe, in plain terms, how customers can reach telecoms carriers and public clouds from inside a building, often called cloud on-ramps. Sustainability pages and annual environmental, social and governance reports set out the company’s stated targets, and investor pages carry results, filings and presentations. For a designer, these formats show how a business with few visible products builds an identity from places, figures and documents.

A hyperscale builder with a telecoms name.

The company changed leaders in 2026. On 12 August it announced that Quy Nguyen, acting chief executive since April, had been appointed chief executive following the retirement of Niclas Sanfridsson. The announcement said Nguyen joined the company in 2016 and had most recently been chief sales officer, and it named Tim Cohen as chairman.

The way Colt DCS presents itself follows its customers. Its website leads with counts of sites and megawatts, and each site page opens with IT power, floor area and a tier label of its own before it turns to connectivity. The home page invites visitors to follow the construction of London 4 phase by phase, and a map splits the portfolio into Europe and Asia. The site is published in English, Japanese, German and French.

One naming trap is worth knowing. The data-centre company publishes at coltdatacentres.net and signs itself Colt DCS, while the network business, Colt Technology Services, uses colt.net. Trade headlines often shorten both to “Colt”, so the full name is the safer label when the two need to be told apart.

For a design guide, Colt DCS shows how a telecoms name can carry over to a business built on concrete, power contracts and land. Compare Telehouse, another London-founded operator with a large presence in Japan through its parent, and Equinix. For this guide we use a slate, a deep teal and a warm concrete grey with a sans, an unofficial interpretation; no product or logo is reproduced.
