Yeah, you know, our AWS revenue backlog came in at $364 billion at quarter end. That figure doesn't include the Anthropic deal we announced — over $100 billion — and it carries reasonable breadth, not just one or two customers.

Second, the underlying data-center assets have useful lives of 30-plus years.
