I asked the Malay Min of Transport if #MH370 data comms system Was disabled before pilot said 'good night' to Malay ATC - he said yes ...
That would be the perfect time to do it as Malay ATC would think nothing of it as voice comms has been established after the failure.
There is nothing unusual in DATA transmission going off line, happens all the time, usually it comes back on its own or after a few resets.
