Hi,
Since the 12/07/2019, ICE stopped getting AWS EC2 Reserved Instances (RIs) information. It will only displays the cost of your on-demand EC2 instances. Therefore ICE ec2_instance costs are on-demand cost only.
This is a FYI only because ICE seems unmaintained (by Netflix and Teevity) and I don't have the skills to fix it. So be aware of this issue before trialing ICE. If anyone has the courage to fix, please ping us in this ticket.
The rest though still seems to work.
