About PUE

We have reduced our actual Power Usage Effectiveness (PUE) to an incredible 1.14.

PUE is calculated by dividing the total amount of power a data centre consumes by the amount used by its IT equipment. A PUE score of around 2 for a data centre is average, while 1.5 is considered efficient.

Anything below this is very difficult to achieve (which is why many data centres don't even try). Only a few other facilities are able to operate at 1.1-1.4, making 4D Surrey one of the greenest data centres in the UK.

IP Transit

Full transit and partial transit, IPv4 and IPv6 supported

What you get

Two options for IP transit the first being ‘full transit’ and the second being ‘partial transit’:

Full transit provides you with all the routes available on the internet ensuring delivery of your IP traffic to and from every location.
Partial transit on the other hand includes just peering connections, which are the routes learnt from other networks that we peer with both privately and on exchanges such as Lonap or LINX.

You also get

IPv4 and IPv6 supported (dual stack)
multiple tier-1 carriers and peering exchanges
fully-resilient Cisco ASR based network
over 40 Gbps of current network capacity
99.999% uptime SLA
and it's available in all 4D and major third party London data centres

How it works

Our IP transit services are fed directly from our Cisco ASR based core network which has over 40 Gbps of capacity. We provide a multihomed feed of routes from Tier 1 carriers such as Level3, NTT and Telecom Italia as well as peering routes on Lonap and LINX exchanges.

Transit is available in any of our on-net locations and is backed by our 99.999% uptime SLA.

How much it costs

Costs are dependent on the quantity of IP transit required (in Mbps) and the location where it needs to be supplied.

Data Centre Interconnects

Dedicated UK fibre network, Transparent, layer-2 connection

Our dedicated UK fibre network provides a transparent, layer-2 connection (with full support for 802.1q / QinQ vLANs) between any of our on-net locations.

Connections are provisioned across our core network and a backup route is provided as standard. This means that should the primary route fail due to a fibre break or equipment failure then your connection will re-route, almost instantly, through another path on our network ensuring your data can still get through.

A list of the 4D connected data centres is available below and if your site isn’t on that list don’t worry, we can more than likely still offer services by using a tail circuit from one of our connected carriers.

Benefits of a data centre interconnect from 4D

Expand your network to new sites quickly and cost-effectively
Benefit from temporary connectivity between sites when migrating
Reduce leased line costs by connecting to a PoP close to your office
Save on bandwidth costs; compared to using Internet traffic and VPN tunnels
Connect to customers in remote locations
Connect to private peering partners or third-party carriers in remote locations
Choose from the following port speeds: 10Mbps, 100Mbps, 1Gbps, 10Gbps
Run your own VLAN tags with no intervention from us

Optional features

Setup and on-going management of switches
Setup and on-going management of your own dedicated firewall
Managed security services (access controls, VPNs, intrusion prevention and anti-virus/anti-spyware)
QoS (Quality of Service)
Separate back-up circuits with fail over for resilience

Hybrid Colocation

VMs connected into your physical hardware colocated in one of our data centres

As a provider of cloud services, 4D can offer fast and flexible Virtual Machines that can be connected into your physical hardware colocated in one of our data centres through a dedicated cross-connect.

This has the major advantages of: additional security (you know exactly where your cloud solution is located); speed (a dedicated cross-connect will ensure real-time speeds between your cloud platform and collocated servers); and cost savings (as you don’t have to send the data from your rack over the internet to your cloud solution) – we literally run a copper or fibre cross connect from your rack into our cloud infrastructure.
