Impact
During a record UK heatwave, a simultaneous failure of multiple redundant cooling systems in a europe-west2 (London) data center left it unable to hold a safe temperature. Google powered down part of europe-west2-a, terminating roughly 35% of the zone’s Compute Engine VMs to prevent equipment damage.
