I didn’t notice that the storms glitched the power enough to take my servers offline. Sorry about that.
I discovered it yesterday. The clue was the temperature dropping in my office to the same as the rest of the house. I didn’t catch it because I kept the office door open so I could keep an eye on the dogs. One of them ate something disagreeable and needed quick access to the back yard. :/
Now that the VMs are back online, the temp in the office is up again. It hovers around 79 degrees if the door is closed. Surprisingly, I’ve become accustomed to it and now the rest of the house feels cold all the time.
