Starlink is a constellation of low-earth orbit (LEO) satellites, not geostationary satellites. That means that the ground station (i.e. subscriber equipment) talks to one satellite as it comes into view, and over time that satellite moves across the sky, and they switch to another satellite. This means the latency is highly variable as the distance changes, but at its lowest is much lower than a geostationary satellite since it is far closer.
54 kg of fentanyl is an insane amount to have all in one place.
Just to put it in perspective:
I’m not sure why they’d stockpile so much in one place, given they apparently have the capacity to manufacture more - unless they were planning to use it to kill people (see: they also had a weapons cache and explosives) instead of to sell as a drug. Or perhaps the 54 kg is an exaggeration and includes packaging and so on.
