Inconceivable? Why?
As to "all surrounding ATCCs on alert" -- what is the trigger for this "high alert" and when would interest become of a high order? There is a time delay between "hmm, haven't checked in yet" and "where the EFF is that plane" of X amount. What do you think X is, in terms of minutes or hours?
Beyond that, on what do you base your set of presumptions?
From what is available to the public, the ATCC in Viet Nam had an interest, and they communicated their concern to a Point of Contact in Malaysia.
(Enroute ATCC asks Departure ATCC "we were expecting this flight, have not heard them check in as expected, were they delayed? Do you know where it is?" That sort of communication would be my
guess. )
