Smart DCC has announced plans to undertake its 2026 Central Switching Service (CSS) Business Continuity & Disaster Recovery (BCDR) exercise within the live production environment, as part of its annual code-mandated testing programme.
The purpose of the exercise is to validate that systems, processes and recovery arrangements will operate effectively in the event of a genuine service disruption. DCC advises that testing within the live environment provides the most realistic assessment of operational resilience.
To support the testing, DCC is proposing that the CSS service is temporarily taken offline while switching to disaster recovery infrastructure and subsequently returning to normal operations. This approach is intended to minimise risks to system data and maintain service integrity throughout the exercise. DCC has confirmed that additional safeguards, including secure backups and pre-test validation checks, will be in place. The proposed approach was successfully trialled in a pre-production environment under operational load.
Proposed Test Dates
Two change windows of up to four hours are being requested between 09:00 and 13:00, with actual downtime expected to be less than 1.5 hours during each event:
-
25 October 2026 – Switch to and operate from disaster recovery infrastructure.
-
15 November 2026 – Return services to normal operational infrastructure.
Industry Engagement Session
DCC will host an industry engagement session to explain the testing approach and provide stakeholders with an opportunity to ask questions and raise any concerns.
Date: 15 September 2026
Time: 15:00 to 16:00
Organisations wishing to attend should register their interest by emailing bcdrteam@smartdcc.co.uk by close of business on 1 September 2026.
