Something worth a thought is that as much as devices don't like being too hot they also don't like to have their temperature change too quickly. Parts can expand/shrink variably depending on their composition. A rule of thumb is a few degrees per hour change but YMMV, depends on the equipment. Sometimes manufacturer's specs include this. Throwing open the windows on a winter day to try to rapidly bring the room down to a "normal" temperature may do more harm than good. It might be worthwhile figuring out what is reasonable in advance with buy-in rather than in a panic because, from personal experience, someone will be screaming in your ear JUST OPEN ALL THE WINDOWS WHADDYA STUPID?

What are normal QA procedures on your behalf? What is the facility likely to be doing? What should be expected in the aftermath?One would hope they would have had disaster recovery plans to bring in outside cold air, and have executed on it quickly, rather than hoping the chillers got repaired. All our owned facilities have large outside air intakes, automatic dampers and air mixing chambers in case of mechanical cooling failure, because cooling systems are often not designed to run well in extreme cold. All of these can be manually run incase of controls failure, but people tell me I'm a little obsessive over backup plans for backup plans. You will start to see premature failure of equipment over the coming weeks/months/years. Coincidentally, we have some gear in a data centre in the Chicago area that is experiencing that sort of issue right now... :-(
