Well said. The electrical load shifts, hydraulic systems, airflows constrained by ice cover, etc, etc, etc. All kinds of things being asked to do stuff outside or at the edge of specifications. Hug your local facilities guys when these things happen. (Or bring them booze.) On Wed, Jan 30, 2019 at 12:58 PM Naslund, Steve <SNaslund@medline.com> wrote:

Yes, in Chicago we will see an increase in home fires because heating systems are being pushed to their limits and people tend to do stupid things like run unattended space heaters and try to thaw frozen stuff in crazy ways. In a datacenter you might be pushing electrical loads while external electrical components are stressed with temperature. I have seen transformer fires caused by the oil inside not circulating correctly. You end up with hot and cold zones in them.
