In 2022, the London data centres of two US tech giants failed as cooling systems broke down during a heat wave, which saw temperatures hit 40 °C. In the US, data centre operators in Florida, a region prone to hurricanes and tornadoes, are building greater resilience into buildings to protect against increasingly common severe weather events.

Data centres (DCs) house the essential compute power and storage for all range of consumer, commercial and public services. Some governments  have deemed them critical national infrastructure. Without data centres, entire sectors, from banking and medicine to scientific research, would collapse. While these giant servers have generally been built to withstand cyber attacks, the risks posed by natural disasters and extremes of weather due to climate change may not have been sufficiently factored in.
