The only interruption I have experienced was following the initial 30-day trial period. I have been the free-tier ARM Ampere A1 resources for 3 K3S worker nodes for over a year now. I did find this note which provides what they consider idle:

Oracle Cloud - Free-Tier Reclamation of Idle Compute Instances

Idle Always Free compute instances may be reclaimed by Oracle. Oracle will deem virtual machine and bare metal compute instances as idle if, during a 7-day period, the following are true:

CPU utilization for the 95th percentile is less than 10%

Network utilization is less than 10%

Memory utilization is less than 10% (applies to A1 shapes only)

Hope this helps anyone who may have been wondering.
