Downtime but limited downtime since the data is stored with triple redundancy across multiple machines in the same AZ. So unless the AZ goes down (which is a different failure than what happened here) you can restart the DB on a different instance pretty quickly and I'm guessing AWS will do it automatically for you.

I don't believe their RDS / EBS has 3x redundancy. With SSD, that would be super costly for them. But if that's correct, that would be incredible.

May not be 3x but it is replicated so even a total instance failure would not make you lose data:

>Amazon EBS volumes are designed to be highly available, reliable, and durable. At no additional charge to you, Amazon EBS volume data is replicated across multiple servers in an Availability Zone to prevent the loss of data from the failure of any single component. For more details, see the Amazon EBS Service Level Agreement.
