How does it practically work? e.g. if I were OVH I just pick any building owner that gives me the cheapest deal, and such owner has absolutely zero concerns as well about safety? Or would OVH own or co-own the building? I am surprised that the landlord didn't have a virtuous conflict of interest in this case.

It's a massive multi-story datacenter used only by them, specifically designed and built for their passive cooling concept, surrounded by other datacenters used only by them. I would be very surprised if they didn't own the building

They specified a price and it was built to that price point. All corners cut as requested.

If you make such strong statements, I would expect that you back it up. For now, it reads as a shallow dismissal, and the guidelines talk about that: https://news.ycombinator.com/newsguidelines.html

Simple comparison. The ones I've been in, including the bad ones, actually had more than adequate fire suppression systems, proper electrical cut outs, fire monitoring systems and certificates proving that they had been audited and tested.

This OVH DC was designed to a cost rather than a safety specification and the risk did not pay off.

> OVH is definitely a complete joke compared to the worst of them

what leads you to say that? just curious

Even the bad ones had proper fire suppression systems and electrical cut outs.
