The room temperature is jumping up about 10 degrees every 1.5 hours and seems to be associated with many trim magnets in the room mismatching at once. I can't head out there at the moment, but I'll drop by on my way out to see if anything is amiss. For the time being, I'm OPS-PRing this because it just seems very strange.
