Pre internet and definitely pre cloud, multiple years of uptime was not unusual. I remember having to shut down a server over 4 years uptime for Y2K and being worried it might not come back.
I see long uptime now, all I see is an unpatched opportunity for bad actors.

This is true. I have in the past worked on more than a few systems with 5+ years of uptime. Was not unusual in the threat environment from 1995-2010 or so.
World has changed a lot since then.
