The datacentre benefits from a full perimeter fence, CCTV which is monitored 24/7, and an access control system.

Full rack customers have lockable rack doors. Datafloors and Power rooms have a gas based fire suppression system using a VESDA early warning system


Our network is multihomed, and is delivered to the datacentre over our route and carrier diverse MPLS network


We are fed from the power grid by a 11kV ring main, with our own substation on site. Continuity is provided by 2 diesel generators and physically seperate UPS's
