I went down a shallow rabbit hole (turns out https://www.reddit.com/r/uptimeporn/ exists ... of course) and found this:

Wow wow wow. I had one that nearly reached 10 years of uptime: a dedicated server at OVH. At some point I just kept it to see how long it'd stay operational without any reboot.
Now, kids, don't try this at home: of course it wasn't secure. At some point it got hacked and that's when I cancelled the subscription for that one dedicated server. I still have other servers at OVH.
But yeah: I made it to 3400 days of uptime. Something like that. Don't remember the price of that one server but it wasn't expensive.
Let say it was an... Experiment.
