Last Thursday night there was a power outage in the office. It took out the circuit that ran the air conditioners in the lab, but it didn't affect the circuit that powers the lab machines. And so the lab ran that way. All night.
In the morning, we walked in to a very hot lab, and started turning off everything we could get our hands on until the air conditioning (which had come back, thankfully!) caught up. So how hot was it overnight?
These (now ex-) ducks were on a table in the lab, too. Tragically, there were no duck survivors.
Consider this your friendly local reminder that servers put out a whole lot of heat.
