Armoured, military-grade nuclear-proof hosting facilities situated outside the M25

Data Centre (The Bunker) overview and site specifications

The data centre is an ex Ministry of Defence (MoD) command and control centre. It was built 30 metres below ground by the UK government to protect people and technology from nuclear attacks.

Our ultra secure data centre facilities are housed within an 18-acre high-security site that addresses every potential threat that can compromise the availability of your business critical applications.

Comprehensive onsite security includes:

• 3.5 metre high perimeter fence
  three metre thick walls
  solid-steel doors
  military electro magnetic pulse protection
  ‘Tempest’ RFI intrusion protection
  24-hour sentry
  MoD-trained guard dogs
  CCTV
  and sophisticated access controls.
  

Admission to the site is via a Guardroom (fitted with bullet-proof glass) which has a vehicular gate with control barrier and electrically operated pedestrian gate.

On site security staff (ex-military and police) maintain a physical presence in the Guardroom and perform random patrols of the site with guard dogs. Patrols of secure areas are also conducted on a regular basis and there is constant CCTV monitoring. Sophisticated infrared cameras cover the site both above and below ground and include a ‘last motion picture captured’ facility with thumbnail archives.

Entry to The Bunker is via a turnstile, operated by an encrypted security card system. All access below ground is physically monitored and recorded by security staff and by CCTV.
