The heatwave that struck the UK late last month resulted in the University of Cambridge’s Dawn supercomputer being knocked offline.Per a report from The Times, the supercomputer was one of several services that suffered an outage on June 27 due to excessive temperatures.Access to the system, which is housed, is expected to be restored today (July 6).It’s believed the incident was caused by a failure with the cooling system at the West Cambridge data center, where Dawn is housed. However, Legrand, the owner of UK cooling firm USystems, which supplied the cooling infrastructure at the facility, said in a statement: “The USystem units operated in accordance with their design specifications and performed as intended throughout the event.”While specific details of the incidents have not been disclosed, The Times cited a spokesperson from the university who said Dawn had suffered “technical issues during the hot weather,” but full cooling capacity has now been restored, meaning researchers who rely on the system would be able to resume their work.Lennard Lee, director of the University of Oxford’s UK Cancer Vaccine AI Scientist & Supercomputing project, was separately quoted by the outlet, saying that although jobs had been paused, there was “no data loss and we aren’t expecting to repeat the work.”This is not the first time extreme heat across the UK has caused issues for the country’s data centers.In 2023, London-based Guy's and St Thomas' NHS Foundation Trust suffered a significant outage during a summer heatwave, leaving doctors unable to access patient medical records and ultimately costing the NHS around £1.4 million ($1.9m).Additionally, the same week Dawn suffered an outage, the Queen Alexandra Hospital in Portsmouth, UK, declared a critical incident, with the National Health Service (NHS) facility stating that chillers had failed at its on-site data center, impacting digital services from Wednesday.As a result, some planned care and appointments were postponed, while those still traveling to Queen Alexandra were warned that "the hospital is very hot."The incident occurred after the UK weather service, the Met Office, issued an extreme heat red weather warning, with the country ultimately witnessing record temperatures of 37.7°C (99.9°F) for the month.A third heatwave of the year is anticipated across the UK this week.
