There has been a nice YT video recently showing how Hetzner operates their DC and their servers: [this video] Was quite surprised that they use custom built server racks with their own custom-made mainboards delivered by OEMs. They even have their own long-term Fan testing rigs and custom HDD failure check setups.

Their buildings are passively cooled so this sounds quite plausible. Pretty fun video showing the realities of their setup [this video]

There's a great YouTube tour of one of their data centres here: [this video] 'Over 200,000 Servers in One Place! Visiting Hetzner in Falkenstein (Germany)' The channel is well worth a subscribe too.

Couldn't agree more, I think Hetzner is probably Europe's best bet on a hyperscaler. One of the more telling indicators IMO is their growing market share outside of the EU/DACH. To add on to the comments about Hetzner building their own custom hardware, they also custom built their own software stack. They rejected the hype that was OpenStack and worked diligently on their own hypervisor platform (that they are incredibly secretive about) and that appears to be paying off in spades for them. Most sovereign cloud plays end up being suffocated by the complexity, and incoherence, of the OpenStack ecosystem. It just becomes impossible to ship. I know Hetzner is working like crazy on a managed Ku

The best resource I know is a tour of one of their data centers. Around minute 6 you get some nice views on their current-gen racks, and later in the video you see the back side, followed by the assembly of the servers. [this video]

Der8auer did some similar videos a few years ago, but in English: [this video] [LINK] The second is especially interesting as it demonstrates Hetzner's unique semi-custom hardware.

Not much to explain, you're absolutely right. Hetzner would have been a much wiser choice here, but advocating any cloud provider at this scale probably has its perks too or he wouldn't be burning his money. Then again, perks only go so long and at some point do come to an end, so this is why he may be writing about costs right now. Take a look at their datacenter in Germany: [this video]

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]. By contrast, the typical data centers people know which have fire suppression systems appear to have much of their key electrical equipment (and control systems) located in the same area or adjoining rooms of the same facility [3] [4] [5] [6]. In fact, there is even a video recording of a UPS failure [7] showing a lucky case where no one was injured and not too much damage was caused. The employee lingered in the
