As a speculation, I’d go further:
Much ground-based Internet infrastructure may be replicated in space so that queries go ground-LEO-ISL-(LEO or GEO)-ISL-LEO-ground. DNS probably first as Dave says with some caching in LEOs, then server farms of CDNs, finally actual data centers. more at https://blog.tomevslin.com/2021/07/computing-clouds-in-orbit-a-possible-roadmap.html From: Starlink <starlink-boun...@lists.bufferbloat.net> On Behalf Of Dave Taht via Starlink Sent: Tuesday, September 19, 2023 5:09 PM To: Dave Taht via Starlink <starlink@lists.bufferbloat.net> Subject: [Starlink] the website for the end of the world John Carmack just kicked off a thoughtful thread over here: https://twitter.com/ID_AA_Carmack/status/1704160299845071328 (Among other things, I would rather like to see DNS services hosted native up there) Starting point: The idea that the internet was created to survive nuclear war is apocryphal; packet routing does provide some resilience, but you will lose internet in an apocalypse. Space based systems are interesting to consider — they tend to be very reliant on ground systems, but it would be technically elegant if packets from one ground station to another were delivered directly, with no other ground interaction. LEO constellations probably need near constant ground help to update orbital ephemeris, and the orbits would decay in a few years anyway, but GEO sats could continue operating for decades if their control software didn’t preclude it. There should be off grid (or even in-space) servers connected to the satellite networks at static IP addresses (so DNS isn’t required). The Website For The End Of The World. What would a sparsely distributed group of apocalypse survivors want to see there? A Wikipedia mirror and some type of forum for communication, certainly. It seems like a good story element, but a little real world LARPing along those lines would be fun. The tragedy would be when all the terminals maintaining a fragile network of communication among humanity shut down due to the account billing servers being unavailable. <https://twitter.com/ID_AA_Carmack/status/1704160299845071328> -- Oct 30: https://netdevconf.info/0x17/news/the-maestro-and-the-music-bof.html Dave Täht CSO, LibreQos
