We describe how doing so not only reduces network traffic, but also allows for fast crash recovery, failovers to replicas without loss of data, and fault-tolerant, self-healing storage.

The other issue is that the data I’m getting back is based on lab simulations where I can add throttling, determine the device that’s used, and the network connection, among other simulated conditions. On that note, it’s worth calling out that there are multiple flavors of network throttling. Real usage data would be better, of course.

De-duplication can prevent multiple copies on disk, but we're out of luck on reducing network costs. That is unlikely given the need for SRI annotations or the unbecoming practice of speeding up high-traffic sites, but not others. One challenge for fair inclusion is the tension between site-count-weighting and traffic-weighting.
