The J-4 network was judged 'fast enough' for normal use, and the IN had
its J-6 couriers for stuff that the IN (and nobles with influence with
the IN, of course) could use. The Imperial family had those disguised
J-6 ships. This is canon

I have no doubt that the various mega-corps had their own fleets of J-6
ships, probably disguised to look like some more common low-jump
courier. I also have no doubt that the Scouts had their own J-6
couriers. Likewise the Solomani spies, though theirs would more likely
to a couple of high-jump ships with wilderness refueling capability that
would be available to a few agents for sending *very* high priority
information back to the Confederation.

None of these entities would find it terribly useful to create a large,
obvious, and really expensive full-scale network of J-6 ships, let alone
one that everyone could use. Thus when things went tits-up, those who
were connected got advance warning (very considerably in advance if they
were far from the event itself).
