Fleet and network: JavaScript Data Grid Demo

Address, data-size and rate types, latency long-tailed so p99 bites

type: ipv4 · bytes · bitrate

This is a fleet and network sheet with address, data-size and rate types, and latency that is long-tailed so the p99 really bites. It shows infrastructure metrics with the right types and the tail statistic that matters for reliability.
