Yes but not by choice Ernest has had health problems and has not been able to work on it. The instance is going to be handed over to a new team when he gets the chance.
I still use kbin social when it is up though I have been using here on kbin.run and I have been testing fedia.io. I did make a matrix to try and keep in contact with other kbin users but I think a lot of us are already spread out to different instances.
I use Linux mint I also tried Lubuntu but it felt slow and clunky and when I tested Puppy linux it seemed okay but I like being able to boot up my laptop without using a usb every time.
Overnight? I thought it would be cleaner during the day because that is when the sun shines. I haven't had an Iphone in a while but I will have a look into grid forecasts. I still use an air fryer not sure what the the wattage is though I would assume it is similar to an oven.
If the heat is negligible I would assume it should not matter as long as you do not charge while your pc is doing a task that uses up to much resources?
Its okay nothing to lose sleep over.
