Question to the Home Office:

To ask the Secretary of State for the Home Department, pursuant to the Answer of 4 February 2016 to Question 22830, whether the Warnings Index Checks system has been affected by high-priority incidents in the last five years.

All Border Force systems and services, including the Warnings Index system, are constantly monitored and closely managed so any arising incidents can be quickly and effectively resolved. Whilst there have been a small number of high priority incidents during the period in question with the Warnings Index system, like other Home Office technology services, it has layers of resilience built into it along with supporting continuity arrangements. This resilience and operational arrangements has enabled controls at the border to be maintained with no suspension of checks at any port since November 2011. The migration in the autumn of 2014 of the core Warning Index services to modern data-centres has significantly improved its reliability and stability.
