@MichaelWhelan One of the things I love about these descriptions of your cover art is that you've clearly read and enjoyed the works in question, and picked up on all the textual details.

There are some pieces of cover art where the artist has clearly only read the blurb for the book, or skimmed the text lightly, and missed important things.

@stefano Fortunately, the only thing that did fail after the aircon was the switch. (And a pair of ear muffs which had been hanging on a metal rail -- they'd melted).

The fire brigade turned up, checked everything, and ran some big positive pressure fans to get airflow through the room from one door to the other to cool everything down.

@stefano About 15 years ago, the place I worked had a supercomputer. One night, the aircon in the machine room failed. The machine kept computing, and the temperature rose. It rose *quite a lot*.

Sadly, the first thing to fail from the heat was the core switch for the room. You know, the one that handles all of the network for everything in the room. Including the temperature alerts.

It was finally spotted about 8am when the security patrol wondered why the door shutters were so hot.
