Environmental and ethical policies.
Bytemark's datacentre uses fresh-air cooling, not common in the UK, and was shortlisted for Innovation in Medium Data Center at the DatacenterDynamics Awards EMEA 2013. Each of its servers is built using efficient power supplies as certified by the 80plus scheme, which requires power supplies to be at least 80% efficient at up to 100% rated load. To reduce the bias found in traditional recruitment processes, the company developed their own anonymous recruitment process in 2015.
