- 🔸 Mount points are AZ-based. In an Auto scaling group spread across zones, you can end up with instances in one zone mounting EFS from a different zone. That might decrease performance and would create an unintended single point of failure. One way to fix it would be [a shell script](https://gist.github.com/bgdnlp/9fd326dc4a23f46bab93a1eade023fe4) that runs before network drives are mounted and edits /etc/fstab with the proper AZ.
