Our supplier will replace the control system of the emergency power supply at our EU9.DUS location in Düsseldorf. The maintenance window is scheduled from September 2, 2026, at 08:00 CEST until September 3, 2026, at approximately 14:00 CEST (September 2, 06:00 – September 3, 12:00 UTC).
The existing emergency power supply will be taken out of service for approximately six hours during this window. A temporary replacement generator will maintain emergency power availability, and all systems will remain protected by the UPS system. No impact on customer services is expected.
This work is required to maintain the reliability of the emergency power infrastructure. Our supplier’s service technician will perform the maintenance in cooperation with our technical team.
