Well right, which came well after the question was posited here.

Wasn't poo pooing the question, just sharing the information as I didn't see that cited otherwise in this thread.

and none in the other two facilities you operate in that same building had any failures.

Quoting directly from their outage ticket updates : 

CH2 does not have chillers, cooling arrangement is DX CRACs manufactured by another company. CH3 has Smart chillers but are water cooled not air cooled so not susceptible to cold ambient air temps as they are indoor chillers.

I’m more interested in how you lose six chillers all at once.

Let's say that hypothetically, a datacenter you're in had a cooling failure and escalated to an average of 120 degrees before mitigations started having an effect. What are normal QA procedures on your behalf? What is the facility likely to be doing? What  should be expected in the aftermath?
