As part of our ongoing infrastructure development plan, one of our UPS clusters—originally commissioned in November 2024 during the early stages of our expansion—will be migrated to a newly prepared power path, Feed C, on Saturday, August 9, 2025.
Feed C is the fourth and final fully diverse power path (A, B, C, D) in our design, completing the last phase of power-related infrastructure upgrades. This enhancement is a key step toward increasing overall system redundancy and preparing the facility for upcoming infrastructure certification.
Planned Work Details
Impact:
- No service (or any form of power) interruption is anticipated
- Affected customers will temporarily lose UPS protection during the migration.
- Customers with dual power feeds connected to other UPS clusters will remain fully protected.
Affected Rows:
- ZA.C1.BB02 (Row 1, bus bar 2) – Racks ZA.C1.R1 - ZA.C1.R15
- ZA.C3.BB03 (Row 3, bus bar 3) – Racks ZA.C3.R1 - ZA.C3.R15
- ZA.C5.BB02 (Row 5, bus bar 2) – Racks ZA.C5.R1 - ZA.C5.R15
- ZA.C6.BB03 (Row 6, bus bar 3) – Racks ZA.C6.R5 - ZA.C6.R8
- ZA.C7.BB02 (Row 7, bus bar 2) – Racks ZA.C7.R1 - ZA.C7.R15
Maintenance Schedule (CEST)
07:00 – Engage external bypass and transfer load to unprotected utility power
08:30 – Migrate UPS input and power panel to new Power Feed C
11:00 – Return load through UPS, perform load verification, battery checks, and confirm system status
12:00 – Close maintenance window
On-Site Access & Coordination
We recommend minimizing on-site activity during this maintenance period. Customers requiring on-site engineering support are advised to coordinate with our operations team in advance to ensure safe access and proper support during the scheduled work.
We appreciate your cooperation as we continue to invest in the resilience and reliability of our facility.
UPS-C - The Hague Data Center
DFDC The Hague will activate its new security access control system at the start of office hours on Wednesday, July 23rd.
As part of this transition, all existing users will be required to re-enroll and sign the updated Facility Rules and Access Policy. Anyone with a valid security profile in the current system may re-enroll without prior authorization from a company representative.
We encourage you to take this opportunity to review and update your SPOC (Single Point of Contact) form to ensure that all authorized personnel are correctly listed. If needed, a copy of your current SPOC form can be requested from DFDC Operations.
The existing access control system will be fully decommissioned by August 8. Our team will continue to provide both on-site and remote access assistance for authorized visitors unable to enroll before the transition until August 31, 2025.
Contact us at operations@dfdc.io or call +31(0)88-2700-200 to schedule an appointment to complete the re-enrollment.
We appreciate your cooperation in ensuring a smooth and secure transition.
Building Security System THG1
As part of our ongoing infrastructure lifecycle program, we will be completing the migration of remaining customer links from legacy switches in our Stockholm environment:
Switches being decommissioned:
- as1.sto1.se
- as2.sto1.se
- as3.sto1.se
Affected IPv4 ranges:
- 94.185.80.x
- 94.185.82.x
- 94.185.84.x
- 94.185.85.x
Scope of Work
- Finalize customer migrations to our new switching platform
- Physically move customer uplinks to upgraded infrastructure
- Decommission legacy switching hardware listed above
Network Enhancements
- New switches offer up to 100G port capacity
- Redundant uplink support for enhanced resilience
-Unmetered options for 20G (copper) and 40G/100G (fiber) available for bare metal customers
Expected Customer Impact
- Brief service interruptions during physical cabling work
- No configuration changes required on your part
All efforts will be made to minimize disruption during the maintenance window
