Not sure if you’re joking but a relatively small datacenter I’m familiar with has reduced oxygen in it to prevent fires. If you were to break in unannounced you would faint or maybe worse (?).
Not quite - while you can reduce oxygen levels, they have to be kept within 4pp so at worst, will make you light headed. Many athletes train at the same levels though so it’s easy to overcome.
That'd make for a decent heist comedy - a bunch of former professional athletes get hired to break in to a low-oxygen data center, but the plan goes wrong and they have to use their sports skills in improbable ways to pull it off.
