A month ago i would have had no idea what you were talking lol. How bad is the paranoia when you are waiting to see if you've isolated the problem or if the powering off sound happens again.
Lol i had a backup generator powering 1 random pump that i forgot about and when it told me i had lost power i spent so fucking long combing through every single thing id made until i found it. The whole time im thinking "is this a glitch? How is everything still running?"
