I’m pretty confident they have efficient fire suppression systems.

They are hosting at least 400,000 servers. They for sure have multiple servers taking fire every single day, and yet it’s the first time it ends up in a catastrophic fire.

The fire suppression system either catastrophically failed, or something out of design happened with one of their inverters, as suggested in the video.

Do servers really catch on fire nearly daily at this scale?

Yes. But normally it doesn't get outside the chassis of the machine.

Normally upon disassembly you'll find a few burnt components and a sooty mark the size of your fist.

According to various sources (here on HN, also their official site) they only have fire detection and not suppresion [1].
