Update - Tamaki Data Centre has identified issues affecting two of the site's three chillers, resulting in reduced cooling capacity.
Teams are actively investigating the root cause and monitoring site temperatures and cooling performance. Our priority is the safe restoration of cooling services and maintaining the integrity of the platform.
Once temperatures have stabilised and cooling capacity has been validated, we will commence our recovery and startup plan. We do not plan to proceed with any start up until at least tomorrow morning. Further updates will be provided as the investigation progresses.
