[Star Wars] What medium are people using to communicate across the galaxy instantaneously?

Basically the title... How is it that faster-than-light travel via hyperspace can take several hours or even days, but people can still send & receive messages instantly, make holo calls, etc?

Is there some quantum entanglement stuff going on?

It's still facilitated by hyperspace, except the Holonet transmissions are boosted by a net of buoys littered throughout the lanes. Which is why it's so expensive to actually have instant Holonet communications at interstellar distances.
