Has anyone noticed that oracle keeps changing the idle requirements for compute instances?

I just checked their docs:

  • CPU utilization for the 95th percentile is less than 20%
  • Network utilization is less than 20%
  • Memory utilization is less than 20% (applies to A1 shapes only)

In May it was 15% and in March it was 10%.

Is there anyway I can keep my compute instance without having them keep reclaiming it?
