I just tracked it on Flightradar24 and saw where it simply dropped off the radar in the NW Java Sea, SE of Pulau Belitung Island. it didn’t have an unsual track and there were a few other aircraft in the same area at the time.

Reportedly there was “bad” weather conditions in the area where it was last known.
Most likely a crashed plane unfortunately.
Looks LN1626 (Libyan Airlines) pulled a u-turn and headed back to Indonesia when they saw the weather at 23:10.
They were just ahead of 8501, who of course kept flying straight into that monster.
