Scheduled Maintenance

Redundancy upgrade – Container 30, Lefdal Feb 14, 2026 08:00-11:00 UTC

Update - We will be undergoing scheduled maintenance during this time.
Feb 02, 2026 - 07:48 UTC
Scheduled - Activity
Redundancy upgrade – Container 30, Lefdal

Location
Lefdal – Container 30

Maintenance Window
14 February 2026
09:00–12:00 CET (3 hours)
* Includes implementation work, service shutdown, and restoration

Description of Change
This maintenance covers redundancy upgrades to the Taiga infrastructure in Container 30 at Lefdal, aimed at improving system resilience and operational stability.

Reason for Change
To increase redundancy and overall stability within the Taiga infrastructure in Container 30.

Urgency
High priority

Expected Service Impact
A service downtime of approximately 3 hours is expected during the maintenance window.
The Pure Storage system in Con30 will be impacted, with all nodes operating in read-only mode during the maintenance. To avoid data inconsistency and ensure system integrity, all services in Container 30 and affected devices in Lefdal will be shut down prior to the maintenance start. Services will be restored once the maintenance is successfully completed.

GlobalSwitch - Planned Maintenance – Chilled Water Migration on Level 5 Feb 23, 2026 00:00 - Feb 24, 2026 00:00 UTC

Chilled Water Migration on Level 5

Location:
Floor - Level 5
Room - E01

Date: 23/02/2026
Duration: 24 hours

Level 5 is currently fed from the old building chiller systems to the CW (Chilled Water) Fanwalls. The Fanwalls are designed with a supply air of 24°C under normal conditions to client’s server intake, with SLA temperatures limits of 16°C (low limit) & 30°C (high limit). Global Switch have built a new chiller system that runs under modern design practices and is more efficient and currently being offline heat load tested.
The new hybrid chilled water system runs at elevated to the old system CW water flow temperatures. However, the supply air temperature of 24°C will remain the same because the Fanwalls were oversized at design for this migration.
Under abnormal conditions estimated for approximately 0.55% of the year, the CHW system will operate in ‘Drift Mode’, meaning higher CW water flow temperatures resulting in higher supply air temperature expected at 27°C, which is still has a good margin to the high limit.
As part of the migration the Fanwalls airflow and valve control will be recommissioned and the modes of operation tested under strict script and control measures to ensure all parts of the system operate as designed.

Purpose of Project
To migrate CHW systems on levels 5 from the current CHW system onto the new NE chiller quadrant, with new water temperatures of 20°C / 30°C.
Systems Impacted

1 fan wall unit will be impacted systematically however with the current loads within the data suite, the data hall will never be reduced to N.

Risk / impact
Increased temperatures in the data halls / Breach SLA’s, risk of damage to equipment

Risk details:
The room temperatures will be monitored throughout work effort.

Risk Analysis
The fans walls will be migrated one unit at a time in a controlled manner. The system will be monitored
to ensure cooling is stable prior to moving onto the next fan walls.

Bulk - Emergency Maintenance - VPN Duplicate Address Detection (DAD)
Completed - The scheduled maintenance has been completed.
Jan 30, 12:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Jan 30, 11:00 UTC
Scheduled - Purpose:
Enable and tune EVPN Duplicate Address Detection (DAD) to prevent MAC flapping and transient loops, improving fabric stability during edge events or misbehaving endpoints. This change is being implemented based on NVIDIA best-practice recommendations for EVPN-VXLAN fabrics and will be applied consistently across the Bulk DC.

Northern Data will implement IP/MAC movement protection mechanisms on their network infrastructure.This is needed to protect the network fabric from excessive network control plane churn which can impact customer experience.If you have floating IP/MAC moves within your AI solution design please note that excessive IP/MAC moves (5 within 3 mins) will result in a 1 hour lock phase.There is no actions for customer to take for this change.

Impact:
No service interruption is expected
No customer configuration changes are required
No impact to existing workloads or connectivity is anticipated

Change window:
Date & Time: 30 Jan 2026 at 11:00 UTC
Duration: Minimal; changes are configuration-only
Affected scope: All customers hosted in the Bulk DC

In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Jan 26, 14:30 UTC
Scheduled - We are preparing an emergency network maintenance on the Ragnar cluster to address ongoing BGP control plane instability that is contributing to packet loss and degraded connectivity.

The change involves adjusting control plane policing parameters on the Ragnar cluster spine and leaf switches, in line with NVIDIA guidance, to prevent BGP packet drops under load. No customer service impact is expected, however brief and transient network blips cannot be fully ruled out while changes are applied.

Scheduled - This maintenance notice is being used to communicate a vendor security advisory issued by NVIDIA. No platform maintenance is currently being performed and no service disruption or customer impact has been identified.

NVIDIA has released a security bulletin addressing multiple vulnerabilities in the CUDA Toolkit.

The vulnerabilities affect CUDA Toolkit versions prior to 13.1 and are primarily related to NVIDIA Nsight tooling components. Under specific conditions, a local attacker with limited privileges could potentially execute commands or escalate privileges when affected tools are invoked manually.

Based on NVIDIA’s advisory and our internal review, the CVE most relevant to our environment is:

CVE-2025-33228
Description: OS command injection vulnerability within the Nsight Systems gfx_hotspot recipe when executed manually
Severity: High
Attack vector: Local access required, user interaction required

There is currently no indication of active exploitation, and no impact to running GPU workloads has been identified.

NVIDIA recommends upgrading to CUDA Toolkit version 13.1, which contains the security fixes.

Customers running CUDA Toolkit versions below 13.1 are strongly advised to review their environments and plan an upgrade where applicable.

CUDA Toolkit 13.1 is compatible with NVIDIA drivers version 580 or newer, in line with NVIDIA’s minor version compatibility guidance.

For full details, please refer to NVIDIA’s official security bulletin.
