Latency is a product decision before it is an infrastructure metric

The source describes an architecture that keeps session ownership in one place and keeps routing deliberately narrow. It treats latency as a complete system property: the public network path, the routing layer, state ownership, and deployment constraints all contribute to what a person experiences.

For an investor, the useful question is not whether a team can quote a lower p50. It is whether the organization can make a latency promise, identify its owners, and continue to improve it as usage grows. That discipline often appears before the metric becomes visible in a quarterly report.
