AIUI, Mode S reporting on the Vector System has been temporarily suspended due to the amounts of data it was accumulating on the network (which reflects the extremely high proportion of traffic which is still Mode-S equipped despite the recent significant uptake in PAW and CAP1391 devices).
ADSB, PAW, FLARM and CAP1391 Vector reports are all still available.
This does not in any way affect Mode-CS reporting on airborne units or MLAT reporting via Rebroadcast.
