It was actually filed about EBS block disks using NVME (on these new instances, there is a hardware card that presents network EBS volumes as a PCI-E NVME device). In certain failure cases since this is a network block store, they can fail for some period of time exceeding this timeout.
The idea of this change is to ensure once they come back the machine is left in a usable state.
Of course, I would not expect to see this on Local NVME disks which is what they announced - that you can now get such instances with local disk as well as EBS.
