Hosted CDR Link FAQ

CDR offers hosted Link helpdesk instances managed by our deployment partner SR2 Communications, a trusted team within the digital rights community, with a proven track record of securely handling sensitive data.

Where do our hosted instances run?

Hosted instances run on SR2's public cloud, which in turn is hosted on servers rented from Hetzner Online GmbH. The datacenter runs on 100% green electricity (certificate) and has stringent security measures in place to prevent unauthorised access. Hetzner holds an ISO 27001 certification (certificate) relating to the security measures in place, and there are no exclusions from the scope in regard to measures mentioned in Annex A of ISO/IEC 27001:2022.

SR2 exclusively and manages the servers from Scotland via mutually authenticated, end-to-end encrypted channels. All CDR Link helpdesk data is stored on a LUKS-encrypted volume with a per-instance key to protect the data at rest. Hetzner staff have physical server access, but strict controls are in place to prevent unauthorised access.
