Surely there must be something that's missing in translation? This feels like it simply can't be right.

It’s accurate: https://www.chosun.com/english/national-en/2025/10/02/FPWGFS...
I agree. No automated fire suppression system for critical infrastructure with no backup?
That may not be a perfect answer. One issue with fire suppression systems and spinning rust drives is that the pressure change etc. from the system can also ‘suppress’ the glass platters in drives as well.
That's why the top-security DCs that my employer operates have large quantities of Nitrogen stored, and use that slightly lower the O2 saturation of the air in the case of fire.
Yes, it's fucking expensive, that's one of the reason you pay more for a VM (or colocation) than at Hetzner or OVH. But I'm also pretty confident that single fire wouldn't destroy all hard drives in that IT space.
Reminds me of the classic video[1] showing how shouting at the harddrives make them go slower.

I'd be interested in if you can even use dry fire suppression on the 5th floor of a building.
At first you think what an incompetent government would do such things, but even OVH pretty much did the same a few years ago. Destroyed some companies in the progress. A wooden floor in a datacenter with backups in the same building …

Battery fire is impossible to suppress.
That's why in high-quality DCs, battery backup is in a separate room with good fire isolation from the IT space.
Yes, the servers still have some small batteries on their mainboards etc, but it's not too bad.
Much harder, but not impossible.

Because it was arson, not an accident
Arson? Sounds increasingly like espionage.
