World Class Standards


Both of our data centres are Tier lll certified by the Uptime Institute (an internationally acknowledged organisation). Green Mountain has been assessed in detail by the Uptime Institute and their consultants over a six month period to ensure compliance. Tier III design provides concurrently maintainable site infrastructure, and the sites exceed that. They are near Tier lV, except for the generators, which are N+1 not N+N because of the very reliable grid supplies. The Uptime Institute’s data centre tier standards are a standardised methodology used to determine availability in a facility. We comply with two forms of Tier Certifications:

  • Tier Certification of Design Documents (awarded DC1-Stavanger and DC2-Rjukan)
  • Tier Certification of Constructed Facility (awarded DC1-Stavanger and DC2-Rjukan

Although Tier III certified does not mean that we do not have the opportunity to build to other layers of certification like Tier I, and the flexibility of our infrastructure support these different requirements.


ISO Certifications

Green Mountain is certified in accordance with:

  • NS-EN ISO 9001:2008 (Quality Management)
  • NS-EN ISO 14001:2004 (Environmental Management)
  • NS-ISO/IEC 27001:2013 (Information Security Management System)

Future of Internet Power

The Future of Internet Power was an initiative started by the largest data centre consumers in North America (Facebook, Adobe, Salesforce, Oracle, eBay etc.) and its mission is to increase the use of renewable energy to power data centres through collaboration with companies, power providers, developers, utilities and policymakers. Through this initiative, they have highlighted six principles to be supported, and Green Mountain was the first co-location provider in Europe to support these initiatives.

Security Design

Monitored by 24h security NOC.

Green Mountain Security Standards

Security Sectioned Centre

The data centres are sectioned into different security zones for the different parts of the complex. The level for each zone may be adapted to customer requirements.

Biometric Access

All access to the centre is controlled by biometric identification system.

Man Trap Entrance

Each person entering the centre will gain access only through a man trap.

Intelligent Video Analysis

The outside and surroundings of the site are continuously monitored by an Intelligent video analysis system.

Security System

Our security system and our routines are in compliance with ISO/EN 27002.

Green Mountain Security Standards

Due Diligence

Below are some important aspects that Green Mountain AS checked in our extensive due diligence of the sites:


  • High stability of mountain rock
  • Location is well protected against extreme weather conditions (does not pose a risk)
  • The region has very little tidal movement (ca. 40 cm). Storm surge tides are registered since 1904. The site has very good clearance to any potential risk (does not pose a risk)
  • Tsunami has never been registered in the region. The topography is such that there is no risk of a flood wave building up approaching the site (depth of 70 m on quayside)
  • There is no heavy industry nor storage of flammable/explosive goods in the vicinity
  • There is no hazardous chemical or oil refining in the vicinity
  • Unprecedented geographical event in fjord system – does not pose risk
  • Checked out risks related to global warming effects


  • High stability of mountain rock foundation
  • Location is well protected against extreme weather conditions (does not pose a risk)
  • There is no heavy industry nor storage of flammable/explosive goods in the vicinity
  • There is no hazardous chemical or oil refining in the vicinity
  • River levels in the area confirmed as not being a threat to the site

Facility Security

All Green Mountain data centres have 24/7/365 security, with security personnel present at all times. Our humble exterior and modest location provide the perfect camouflage for added IT security.

Fire Suppression

DC1-Stavanger’s location inside a mountain enables the facility to be made air-tight and hypoxic air ventilation used as a fire suppressant – A fire can’t occur because the combustions process does not receive enough oxygen which is reduced to about 15% (from 21%). This corresponds to an altitude of approx. 3.000 m. Oxygen level is constantly monitored with display screens in every client room ensuring the system is fully operational at all times. The mechanical equipment used to achieve this is duplicated N+1.

Other advantages of hypoxic ventilation:

  • Reduces/limits smoke creation
  • No secondary extinguishing damage (corrosion, environmental damages, toxic gasses etc.)
  • No hard disk failures due to a release of gas fire extinguishant.
  • Creates optimum operational environment
  • Avoids any corrosion damage from saline air
  • N+1 solution. No downtime to replace gas if a discharge occurs.

EMP Secure

Electro-Magnetic Pulses (EMP) is a threat to data systems and data centres in general.
Solar flares or solar storms produce radiation across the electromagnetic spectrum at all wavelengths and may in extreme cases cause problems for computer equipment. Also, volcanic eruptions / volcanic activities may cause energy-rich EMP activity that potentially could disrupt or destroy electronic equipment.

The best protection for such EMP activity is locations underground. Recommendations are to have a minimum 5 m earth coverage to absorb the energy. The server rooms have coverage of 100 m of granite, so Green Mountain is well protected against EMP energy. The location was originally built by NATO to withstand a nuclear bomb. The main characteristics of the site are maintained in the rebuilding process into a data centre.

Risk Mitigation and Disaster Recovery

We have 2 data centres in the Green Mountain group. DC1-Stavanger is located just outside Stavanger on the south-west coast of Norway on an Island, connected to the mainland by road/tunnels. DC2-Telemark is on the edge of the town of Rjukan. It is 2 hrs by car from Oslo International Airport, and there is a small airport within 30 minutes It is in the heart of hydro generation in Norway with multiple hydropower stations within the near vicinity.

Our two facilities are located on separate power grids; approximately 30km apart from each other, which provides for a full disaster recovery deployment in the Telemark area if required.
