I came across tour of Hetzner datacenter[1] and it looks like a completely unprofessional setup, like castle on stilts. Does not inspire confidence.
Yeah I've seen way, way worse. Stuff like power cables zip tied to network cables and fibre lines. DUST. delerict hardware just sitting everywhere.
This is nice. What are you looking for, IBM dudes in white shirts running around?
Ever been in a firewall/router manufacturers R&D/QA lab room? Those are so, so much worse. This is heaven by comparison.
depends how localized the fire extinguishers are and how the power is distributed which is hard to see from the video
not sure what you expect, using 1-2U boxes or blades or something wont change the setup that much, it pretty much boils down to 'how many machines will die in the same time on power/fire' and how can we cool them as cheap as possible.
