A streaming service places its origin servers in a region with a relatively clean electricity grid but a long latency to its main user population and relies on a CDN with edge nodes near users to deliver the actual video content. The reason this architecture works well despite the origin being far from users is that:

Question

Accepted Answer

The CDN serves the bulk of user requests from edge caches, so most user-perceived latency depends on the edge rather than the origin's distance.

Answer

Streaming protocols are inherently latency-tolerant, and the location of the origin server has no observable effect on the user experience for any video service.

Answer

The origin region's cleaner grid produces electricity that travels directly to the edge nodes through the CDN provider's private network.

Answer

Modern streaming uses adaptive bitrate, which automatically compensates for any latency between the origin server and the end user.
