For those that can find out
There have been many attacks on EUROCONTROL and ICAO and the ANSPs for not closing the airspace in East Ukraine. Many airlines carried on flying through the airspace from Ukraine into Russia. One airline that would be expected to be routinely on routes into Russia would be Aeroflot (and of course other Russian carriers).
I don't suppose anyone here could have a look and see if Aeroflot started avoiding the area just after the Buk missile carriers arrived?
