Something just exploded in my server room, at least I think that's where it came from. Was a loud bang, sounded almost the same thing as when you throw a really large breaker, very clunky type of metalic sound. I keep replaying the video footage and I have no idea what it even was. I don't have any alarms for anything but still does not bode well... The sound could be heard from wood stove area too, but it's a bit more muffled, it sounds more local from server room footage. Checked all my batteries and servers look fine too. Really weird one.
