This policy covers all services that use a gsi-family domain name (gsi.gov.uk, gcsx.gov.uk or gsx.gov.uk), but organisations must prioritise their email. It provides guidance to help organisations migrate their email service to a public cloud or other internet service. It is intended to aid public-sector organisations, as well as commercial and other non-government organisations that use a gsi-family domain name.
Organisations must complete their migration before March 2019.
