I would be surprised if there is a lot or even any cache on the satellites itself. Fast large storage that's radiation hardened would be extremely expensive, and they have a lot of satellites. The satellites are low enough that general radiation isn't that bad, but every pass through the South Atlantic Anomaly would risk damage if regular flash storage is used.

You could put DNS on the sat I suppose, but other than that you'd need to have a full Netflix/Cloudflare node, and the sats are far too small and numerous for that.
- michaelt 2y agoI'm working on a new type of protocol so that when there's a large-scale online event like the superbowl or a major boxing match on a streaming platform, satellite and cable internet providers will be able to send a single copy of the video stream on the uplink, and using a new technique we've named "casting the net broadly" multiple viewers will be able to receive the same downlink packets which we believe will have excellent scalability, enabling web-scale streaming video.
