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.
