Dec 04, 2025 - 08:00 UTC
Scheduled - Summary: Pre works as identified on the RCA
Risk : Low, no service impact or redundancy level decrease from design.
Start Date: 04/12/2025
End Date: 09/12/2025
Overview:
Software and firmware updates to our cooling distribution units (CDU) to optimize the current system´s response. The guardrails currently in place can be further exploited by increasing thresholds without causing concerns with safety boundaries. Additionally, we will be installing pressure sensors throughout our PCW to provide better visibility and control, by having more granular data available for our systems. A second pressurization unit will, as well, be brought to service to provide better response times and resiliency when we need to pressurise/ de-pressurise our PCW line.
Recommendation:
Our recommendation is to move forward with the above under supervision from Start Campus operations team.
Objective:
Overall objective is to optimize our system´s response and behavior. Improving software thresholds together with new field instruments will increase our system´s performance.
Procedure:
Activities will be completed in different days to avoid clashes and major impacts. Software and firmware updates, for CDUs, will be completed on a "one at the time" basis so system functionality will be maintained. Pressure sensors will be installed in existent pockets and second pressurization unit will be assembled without causing disturbances to the PCW system.

Location -
Lefdal – Container 30
Maintenance Window -
10 January, 2026 at 10:00 CET
A 2-hour implementation window:
Start: 10:00 CET
End: 12:00 CET
Description of Change -
This change involves work on the Taiga network infrastructure located in Container 30 at Lefdal. The goal is to increase resilience and stability within the Taiga network environment.
Reason for Change -
Increase resilience in Taiga network container ( Container 30)
Urgency -
Medium Priority
Expected Service Impact -
Service interruption is expected to be minimal, as the majority of the Taiga network equipment will remain operational in different container
Our team will monitor the process closely and take immediate action to reboot any affected hosts, minimizing any potential impact.
If you have any concerns during this maintenance window, please contact Taiga Cloud Customer Support via the ticket portal or email cloud-support@taigacloud.com.
