Starting about two hours ago, the air conditioning unit that sits, roughly, right over my head behind the drop ceiling, suffered some kind of fault. It has, ever since, been emitting a loud, high-pitched noise to alert us of this fact. Friendly, in its way, but headache inducing.
My manager reports that someone from the facilities group is on the way to relieve us from this over-zealous alert.
I give him 30 minutes to get here and then I'm bugging out.
