What it is

Mark Handley of UCL looks at how SpaceX's November 2018 revisions to the Starlink constellation affect network behavior. The video visualizes the orbits and routing and estimates latencies, building on his earlier video and research paper.

Why Hacker News recommends it

HN points to Handley's simulations whenever Starlink latency comes up, as the best visualization of orbits and why laser links could beat fiber over long distances.
