Wondering what else, besides anycast DNS, could be worth hosting up there.
There is this study going on too: https://cordis.europa.eu/project/id/101082517

John Carmack just kicked off a thoughtful thread over here:

(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.
Recent experience about war teaches many things. (if war is what you
mean by end of world, because there could be other reasons for end of
world, like viruses, volcanos, metoerites and others).
In an advanced war, the destruction of sats could appear relatively
early. At that point, it would make not much sense to put many eggs up
there on sats.
In a controlled war, the sats might indeed be spared - maintained there
in agreement, but then we wouldn't talk about 'end of the world'.
However, it is not known whether there could be such thing as a
'controlled war' when people get very upset at each other.
For the contents of an 'end of the world' website, provided it could be
reached somehow, maybe among some underground shelters, I'd suggest the
following:
- prayers (I am not a believer right now, but at the end of the world
one never knows).
- description of a means to measure time when light (Sun, starlight) is
absent, so no shadows for sticks.
- description of methods to communicate on a longer distance when
electricity and batteries are unavailable.
- other similar survival's expert advice.
