去年三月在「OVH 法國機房 SBG2 火災全毀」這邊有提到 OVH 的機房大火事件，最近有些情況總算被揭露出來了。

在 Hacker News 上看到「OVHcloud fire report: SBG2 data center had wooden ceilings, no extinguisher, and no power cut-out」這篇這個月月初的報導，裡面題到了一些情形。另外對應的討論在「OVHcloud fire: SBG2 data center had no extinguisher, no power cut-out (datacenterdynamics.com)」這邊可以看到。

其中一個是在講消防隊花了三個小時才把電力切斷，因為電力室外面有非常強力的電弧：

According to the report firefighters on the scene found electrical arcs more than one meter long flashing around the door to the power room, and it took three hours to cut off the power supply because there was no universal cut-off.

另外電力室本身的設計也不利於防火 (木造天花板？)，而且電力管道也沒有隔離：

The power room had a wooden ceiling designed to withstand fire for one hour, and the electrical ducts were not insulated.

另外因為節能的設計，他們設計了多個通道讓外部的空氣容易進入 data center 交換熱量，但這也導致了火苗很不容易熄滅：

Once the fire escaped from the power room, it grew rapidly. The report says that "the two interior courtyards acted as fire chimneys". JDN claims the spread of fire may have been accelerated by the site's free cooling design, which is designed to encourage the flow of outside air through the building to cool the servers.

OVH 目前因為訴訟的關係，基本上都是拒絕評論...
