Downtime but limited downtime since the data is stored with redundantly 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.
edit: Remove triple as not certain about level of redundancy
- truetraveller 3y agoI 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.
- marcinzm 3y agoMay 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.
