French media covered this earlier in March, but I didn't see the english language reporting until now. https://www.journaldunet.com/web-tech/cloud/1509749-enquete-sur-l-incendie-d... OVH has not released its own report about the fire at its SBG2 datacenter on March 10, 2021. The Bas-Rhin fire service, the local responding fire service, issued its report this month. - absence of an automatic fire extinguishing system on the site - a wooden ceiling with a "fireproof" capacity of only one hour with non-insulated technical ducts. - the two interior courtyards acted as fire chimneys - absence of a general electrical cut-off device - Electricité de Strasbourg, the site's electricity supplier, arrived on the scene at 1:20 a.m., but its teams "encountered difficulties in cutting off the electricity." - The site's power supply will be effectively disconnected at 03:28. "At this time, current is still present in the inverters (designed to take over in the event of a cut, editor's note)", specify the firefighters in their report. https://www.datacenterdynamics.com/en/news/ovhcloud-fire-report-sbg2-data-ce... Update: In response to a request from DCD, OVHcloud said that it could not respond in detail to the fire report, as it is still working with its insurers and government agencies on a formal report. The company did point out that the fire report is not from a data center expert, but was not able to give a date for when its own report would be released.
