Successful Business Continuity Management test with client participation

On Saturday, 11 October 2025, Clearstream Banking S.A. successfully performed a Business Continuity Management – Systems Unavailability test in which it offered clients the opportunity to participate.

The objective was to simulate the loss of one of the two data centres and to simulate the loss of one of the cloud services availability zones we use while production processing continued, thereby verifying that business activities could still be performed from the remaining data centre and the remaining availability zones.

Our IT and business teams validated the availability of business-critical applications and performed day-to-day business activities in Frankfurt, Luxembourg, Prague.

Clients had the opportunity to participate from locations in Europe and Asia and reported successful results.

This again confirms the reliability of our systems and the continuous attention we pay to safeguarding our clients’ business activities.

Many thanks again to our clients who dedicated time and resources to participate in this exercise.
