We're closing the same, since the infrastructure dealt with the heatwave flawlessly. Outside temperatures were hitting 41°C past days.

Monitoring
We're currently closely monitoring the ongoing heatwave across Europe, with daytime temperatures exceeding 40°C. To ensure business continuity, we implemented several measures in advance:
- The datacenter is cooled using a chilled water system, which has been verified to operate within the manufacturer's specified ambient temperature range - Adiabatic pre-cooling has been added to the chilled water system to reduce the temperature of incoming air before it reaches the mechanical cooling equipment - The datacenter is currently operating in recirculation mode. Outside-air free-cooling dampers are closed to maximize cooling efficiency during the heatwave. - Grid power quality is continuously monitored, and standby emergency generators are available to seamlessly take over the electrical load if required - Our datacenter on-call engineers are continuously monitoring operational metrics, with particular attention during peak temperature periods
We do not expect operational instability following implementations made since 2025.
