The south indian ocean is the re-entry site for the 2nd stage of their next starship flight test, which will (should) re-enter in one piece so the risk of falling debris is certainly not trivial and unfortunately the size of the hazard region is also not trivial.
They've rescheduled a few times now and each time operators flying in this region have to shuffle things around.
They're also going to deploy several fake starlink sats which will re-enter in the same area but with no control AFICT so those will cover more area.
