As part of our continued infrastructure upgrades following the April 9 utility power maintenance, we will be performing critical work on Saturday, May 3, 2025. During this window, we will migrate Power Feed A at DFDC The Hague to a newly deployed UPS cluster.

This activity is part of a broader effort to increase power system redundancy and prepare the facility for our upcoming tier-3 design implementation.

No interruption to Feed A is anticipated. However, Feed A will be temporarily unprotected during the migration. Customers with dual power feeds and operating on UPS Cluster B will remain fully protected throughout the maintenance.

We recommend minimizing on-site activity during the maintenance period. Customers with a need for on-site engineering support are advised to coordinate with our operations team in advance.

We appreciate your continued cooperation and understanding as we improve the resiliency and capacity of our critical infrastructure.
