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.
