Aren't they supposed to have 3 copies of everything? If so, two datacenters going offline at the same time should mean almost zero data loss.

No.
_You_ are supposed to have three copies of everything - and two of those should be off AWS.
Yeah yeah I know about 3-2-1.
But when I put data on normal S3, isn't my money supposedly paying for triple redundancy?
Look, here's the documentation: https://docs.aws.amazon.com/AmazonS3/latest/userguide/DataDu...
"S3 Standard, S3 Intelligent-Tiering, S3 Standard-IA, S3 Glacier Instant Retrieval, S3 Glacier Flexible Retrieval, and S3 Glacier Deep Archive redundantly store objects on multiple devices across a minimum of three Availability Zones in an AWS Region. An Availability Zone is one or more discrete data centers with redundant power, networking, and connectivity in an AWS Region."
As far as I've heard before that's not with parity and three zones means three copies. But when I search now I see things about 5+4 parity, any insight here?
