X-Boats are a (relatively) fast communications network running across the Imperium. Think Pony Express and you'll have the right idea. The basic network consists of (I think) small Jump-4 craft with 1 crew and no maneuver drive(!). The idea being that they jump into a system, squirt their information to the next waiting X-boat in the chain which jumps out to the next system. The incoming X-boat is then picked up by a tender, and refuelled ready for the next jump. Must be manned by fairly rugged (or slightly loopy) individuals who spend a week at a time in a small ship with no-one to talk to. Don't know why it's not automated...
Given that messages at this rate travel roughly 4 parsecs/week i.e. about 13 ly/week, it can still take a long time for news to cross the Imperium.
I would also suspect that the Navy and probably some megacorporations maintain a Jump-6 capable equivalent to keep ahead of the news...
hope that's useful,
Mark B
