As part of our ongoing infrastructure expansion, we will perform scheduled maintenance on ATS-C and UPS-C to support the installation of an additional distribution panel for power feed C.

The maintenance window is scheduled for:

Saturday, March 28, from 07:00 to 17:00

Impact
- No service interruption is expected.
- During this window, both ATS-C and UPS-C will be unavailable.
- All loads normally supplied via DIST-C1 will be transferred to ATS-D via external bypass.
- Power will remain continuously available throughout the maintenance.
- Systems will operate without UPS protection for the duration of the window.
- Generator-backed protection will remain available via ATS-D.

Affected Scope

All infrastructure connected to DIST-C1.

Additional Notes

This maintenance is required to expand capacity and improve long-term resilience of the power infrastructure. Increased activity from electricians and contractors is expected during the window. Certain shared areas, including the loading bay, may be temporarily restricted.

If you have any planned shipments or require access during this time, please coordinate with our operations team in advance.

ATS-C / UPS-C / DIST-C1

During a recent routine inspection at DFDC The Hague, we identified an installation issue with Busbar A in Row 5 of Zone A (ZA.C5). As part of our ongoing program to audit and modernize older infrastructure, we will be performing corrective maintenance to ensure continued reliability and safety.

To complete this work, Feed A of Row 5 will be temporarily de-energized during a controlled maintenance window.

Customers with redundant power supplies connected to Feed B or Feed C are not expected to experience service disruption during this time.

The maintenance window is scheduled as follows:
Date: March 05, 2026
Time: 11:00–13:00 CET

Preparatory work that does not impact services will begin earlier that morning. The maintenance will be carried out by our certified electrical vendor together with our infrastructure team.

We appreciate your understanding as we continue investing in the resilience and quality of the DFDC facility. If you have any questions about your specific setup or redundancy, please contact our support team.

Zone A - Row 5 - Busbar A (ZA.C5.BB1)

Earlier this morning around 7:16 AM GMT+01:00, a utility power event failure occurred at the facility. During this event, the electrical load on ATS-A did not transfer to the generator as expected. As a result, the UPS batteries supplying ATS-A were depleted, causing a power outage on this path.

Our engineering team is actively investigating the root cause of the transfer failure on ATS-A and is working to restore full redundancy as quickly and safely as possible.

Current status:
- ATS-A: Impacted by power outage (under investigation)
- ATS-B: Operational
- ATS-C: Operational

Services connected to ATS-B and ATS-C remain available and unaffected. We are currently working on restoring power to customers behind ATS-A.

We will provide further updates as more information becomes available or once the issue has been resolved.
