> Hetzner Falkenstein was toured recently by a YouTuber and I didn't spot any fire suppression systems in the video [1]. OVH SBG1 (which was partially destroyed by the fire that wiped out SBG2) used shipping containers which also didn't appear to have any fire suppression systems [2]. They can definitely shut the vents at the top so that the problem with air circulation during a fire wouldn't appear. Furthermore, their dcs are only on one level, so it couldn't spread upwards. I don't know if they got an external fuse/switch, but it seems likely that there's something between substation and the individual dcs. As for fire suppresion, I tried to spot one but couldn't either. But he never shows all parts of the DC, it could be in a part that's not shown. However, with the design they use, if they can ensure that a fire is contained within one DC, the damage would probably be comparably low, especially if you consider the space they have between the racks.
