Yeah, you can do stuff to maximize uptime but if it needs to stay up that badly you have to consider the case of the hardware needing to be turned off at some point.

I'm not, it's a bug and should be fixed. But I think if anything is powered for 3 years straight it's a bit concerning.
Otherwise you're liable to find things like that somebody started something by hand 2 years ago, and at a critical moment nobody quite remember what the command was.
