I just checked my local network website, I started running it in 2021, but havent touched it since mid 2022. I might have checked to see if the computer(raspi4) is on since then, I can't remember why I would have done this, maybe to show a friend. Somehow not only is the computer still on(How? shouldnt a power outage have turned this off at some point?), but the server still is working perfectly. I genuinely don't understand, but its recording sound and temp data as we speak. To be fair, I did mess around in 2021 to ensure things were robust since I was working on an Embedded project at the time.
