Google already does preemptive VMs where an instance can go down if it's needed elsewhere. It's something you can design your services to handle easily, if you aren't already doing so.

Why wouldn't cloud providers be aware of how long a specific CPU has been up and plan around it? Also, do cloud providers generally never reboot their systems?

In AWS, if you keep a long running VM, it will keep running in the same server, even if degraded afaik. Even a reboot won't migrate to a new server. You have to shut it down and power it back up. This I learned back in 2019, so it could have changed but I doubt it.

GCP also does live migration for standard instances.
