I was listening to sessions from AWS Re:invent last night. What jumped out at me was the claim of 11 9's for S3. How many of those 9's have they blown through with this outage?
That's a durability target, not an availability SLA. Durability != Availability.
That makes more sense (since I was listening to it in the context of a conference session, I'm not sure if I heard a distinctive term being used, though I'm sure they're careful about the language they use)
That's for data retention, S3 only guarantees three 9's availability.
