ants_a is correct. Also, our NVMe storage is ephemeral so you aren't recovering from a power loss anyways :)

Disclaimer: I work at AWS, not on EC2.

Locally attached disks are not ephemeral to instance reboots/power failures. However, the disks are wiped after instance terminations. On the official EC2 product pages this is called "instance storage" not "ephemeral storage."

TIL, this is really good to know! Do you know offhand if this is a new feature, or have I just always been wrong

It's been that way for a long time - years at least. You can reboot but not 'stop' and of course not 'terminate.'
