Connectivity and cloud services

Datum connectivity map

Datum connectivity services are available to connect between your sites, to other data centres, to the internet and to public and private clouds. 

Using a dedicated fibre network linking core sites around the UK, and working with best-of-breed suppliers such as BT, Virgin, Level3, Vodafone, SSE, Zayo and Interoute, Datum connectivity services provide resilient links at any bandwidth across the UK and to Europe and the USA.

Our highly resilient UK fibre network delivers robust connectivity using the latest Optical Transport Network (OTN) switching for the most demanding of requirements. Options include fibre-optic services such as Dark Fibre and Optical Wavelengths, as well as traditional leased lines, MPLS and ethernet. Interface solutions such as IP Transit, Cross Connects and Global Connectivity are also available.

Flexibility and choice

Datum is both a cloud and carrier-neutral data centre. You choose your Point of Presence (POP) and you choose your bandwidth supplier. We do not bundle rack space with a specific comms supplier. Instead, we encourage an internal communications marketplace, with telecoms companies vying to provide the best service for the largest number of customers. You may even wish to maintain agreements with several suppliers for the purposes of redundancy.

The growth of Farnborough as a data centre cluster has encouraged multiple providers to build out their network throughout the area, enabling Datum clients to benefit from a ready set of connectivity options. With multiple-fibre providers and a latency to Slough and the City of London of less than 1 millisecond, we are well placed to help clients find the right connectivity package.

Clients receive regular reports detailing all of the available networks that we provide, and listing services, pricing and availability. There are no third parties or resellers involved; your contracts and SLAs are direct with the provider.

The connectivity providers present in our data centres will provide the usual range of connectivity from basic internet bandwidth through to Tier 1 network provision. We also provide fast redundant WAN links to other connectivity hubs.

Connectivity services

Datum Dark Fibre offers a layer one connection with the ability to completely control the network environment. Anything and everything that passes down the fibre is controlled by the operator, whose own network team light and manage the connection.

Datum Dedicated Fibre is a solution that provides the user with all the benefits of Dark Fibre, without needing a specialist networking team in place to manage it. Dedicated Fibre offers a layer one connection with the control you need, while outsourcing the management of that connection to technical experts.

Datum Wavelength enables you to lease a Wavelength in a managed fibre network giving you the security, capability, uncontested nature and speed of a single leased dark fibre, at a greatly reduced cost and infrastructure requirement.

Datum IP transit allows your traffic to take full advantage of our triple-node resilient Tier 1 carrier connections to access the public internet. Datum IP Transit service runs over Tier 1, IPv6 enabled, optical IP networks.

Datum Multiprotocol Label Switching (MPLS) is a scalable network management solution. Data packets are assigned labels and find the quickest route at the time. This allows us to create efficient, private end-to-end circuits across our network for our clients.

Datum multi-service leased line is more than a connection to the internet. Datum can link you directly with Public Cloud services, backup facilities, co-location, or any of our on-net partners’ hosted services, such as virtual desktop or VOIP, all with guaranteed quality of service.

Datum Wireless WAN solutions avoid the costly process of introducing cables into a building, as a work-around for difficult to reach locations, or as a cost effective backup.

Datum Office Connect enables you to store your data and systems centrally in a local data centre, giving you the security of cloud backup combined with the peace of mind and serviceability of being able to touch it.

Datum Cloud Connect provides client connects to our network at any POP or on-net data centre.

Datum’s Farnborough data centre is home to a diverse range of organisations who share a requirement for highly secure and resilient colo to house and connect their business-critical IT infrastructure.
