Which would be embarrassing if this had happened to a product offering such an SLA. Instead, this is just zone-local HDD storage. It will only affect customers

Which would be embarrassing if this had happened to a product offering such an SLA. Instead, this is just zone-local HDD storage. It will only affect customers that decided to run a system in a single site, making no snapshots or using cross-region replication, etc. Which may be quite a few seeing as there seems to be this misunderstanding that VMs "in the cloud" have physics-defying redundancy attributes. (Not saying you have this idea, just that multiple clients have expressed surprise when their single-VM setup goes down because "isn't this what the cloud is for?".)
