Dimension Data Companies

Dimension Data Advanced Infrastructure (DDAI) is a specialist building services and IT systems integrator that helps clients to plan, build, support and manage their building infrastructures. In October 2010, Nippon Telegraph and Telephone Corporation (NTT), one of the largest global telecommunications service providers, acquired 100% of Dimension Data plc for GBP 2.1 billion, making Dimension Data a wholly-owned subsidiary of the NTT Group.

Dimension Data’s systems integration business provides specialist IT infrastructure solutions across networking, data centre, unified communications, security, desktop and contact centre technologies, generating over 77% of the Group’s annual revenues. Dimension Data’s other businesses generate the remaining 23%.

Key Dimension Data companies


Internet Solutions
Internet Solutions is a pan-African communications services provider of IP-based connectivity, communication, data centre and carrier services.

Connectivity solutions include corporate Internet access, virtual private networks, community-based connectivity services as well as fixed and mobile broadband.

We use our IP-enabled network to facilitate communication, with services including voice, messaging, facsimile, mobility, and unified communications.

Our data centre services provide both physical computing infrastructure and applications in the cloud, primarily through hosted data centre services such as lodging, hosting, and virtualisation of servers and storage.

Our carrier offerings include self-provisioning of wireless, satellite and local loop services and participation in undersea, national and metropolitan fibre networks. To offer our clients the widest choice of services and geographic footprint possible, we have supplier relationships with in-country telecommunications carriers.

Express Data
Express Data distributes ICT technologies, from a range of leading vendors, in Australia and New Zealand. For many of these vendors, Express Data represents their largest channel to market in the region.

Express Data operates a world-class distribution system and is recognised as a leader in networking and collaboration, business productivity, data centre, video and design, security, mobility, cloud services, and business connectivity.

Typically, the technologies represented by Express Data are relatively complex to implement and support. We add value by managing the needs of the reseller channel at a lower cost than the vendors could achieve themselves. In addition, many resellers have migrated to a services-led model, outsourcing more product fulfilment tasks to Express Data.

With the shift from capex to utility-based models, Express Data acts as an aggregator for the reseller channel, providing billing, administration and collection services across multiple software and service providers.
