Right? What temperatures would servers continue to operate at, but would be unsafe for humans?
The air was too hot to breathe.
I had to take and hold breath to jump in to shut down most important assets.
There was redundant air conditioning except for exactly one element: air inlet on the roof. A thin plastic bag blocked it.
Nice case to prove that plastic waste is hazardous though!
But the offset was definitely increased understanding of the concept of single point of failure.
Never knew about the squirrel angle, thank you!
This may be a hint that you don't want to colocate where I stuff my machines ;)
EV1 was pretty reliable right up to the point that it wasn't. Taught me some good lessons about multi-DC availability. Some of which were recently re-learned by the folks at OVH.
Actually, I apologize that was a huge presumption.
When _I_ am in a sauna I'm normally not fully clothed and running around in a stress induced panic.
Also 60 degrees Celsius would mean it made an appearance here:

Given that the highest recorded air temperature on earth is 56.7 degrees, you may wish to revise your last sentence.
I was thinking 40 degrees. Given "average" isn't implied by "really hot", I'd say your 40 degree figure falls in line with what I had in mind. But you're right that it's still a big jump to 60 degrees.
Maybe I shouldn't have put vague comparisons in my post because it's rather distracting from the core point that the GP got their Celsius and Fahrenheit mixed up.
When outside temperature is equal or higher than body temperature the only way to expel heat is through sweating. For this the air must by dry enough (wet bulb temperature less than body temperature). https://en.wikipedia.org/wiki/Wet-bulb_temperature
If body can't expel enough heat it results in eventual death.

But it seems like 175F (80C) would be a normal-ish range. temperature.
Probably people die in saunas all the time in countries where it's popular, like they sometimes do when eating, walking, or sleeping or watching tv.
80 degrees C would generally be the hotter end of spectrum. Some go as low as 40 degrees C
No Celsius. Admittedly 140 C is very hot (but not unheard of) for a sauna and you should probably not be in for more than 2-3 minutes max at a time. 90-110 C however is pretty standard and really nice. I can highly recommend giving it a try.

Given someone died at 110 degrees C in a world championship, I'd wager 140 isn't "hot but not unheard of" and 110 isn't "pretty standard" like you claimed.
Perhaps not the PCB itself, but there's typically lots of thin wire around with thin insulation.
A lot of DCs after 2000 went from cold to warm based on the failure rates not changing.
If you get a chance to tour HE Fremont (the old Apple factory), it's not cold.
Factoid: most startups in SV started with a rack in a closet, that one day lost air circulation or cooling and went to the boiling point. I recommend people monitor the temp and cut 2 inches off the bottom and top of their closet door to allow passive cooling while you drive back to the office.
