MYSTERY SOLVED!

I have spent one day researching something else, but I have solved the mystery of the MH17 routes that were somehow changed after the crash.

The only reliable data source for MH17 flight data is Flightradar24.com. FlightAware does not have coverage for Ukraine. Both networks rely on volunteers to receive ADB-S data and feed it into the network. FlightAware​ does not have anyone in Ukraine, As Mike from FlightRadar24 explains, the FlightAware data was extrapolated and somehow corrected manually afterwards:

"Flightaware didn't have any data in this area. They have added one raw of data from unknown source manually afterwards." http://forum.flightradar24.com/threads/7777-Malaysian-B777-MH17-crash-poss-shot-down?p=55040&viewfull=1#post55040

Here is the full FlightAware data from the day of the crash. As you see, the last reliable datapoint is at 14:11:13 CEST. Someone has manually added one more point at 15:19:59 CEST. The source of the data is indicated as WMSA / SZB or Sultan Abdul Aziz Shah Airport in Malaysia. http://fr.flightaware.com/live/flight/MAS17/history/20140717/1000Z/EHAM/WMKK/tracklog

If you look at the data for the previous day, you will see that all points after 13:55:48 CEST are estimates. http://fr.flightaware.com/live/flight/MAS17/history/20140716/1000Z/EHAM/WMKK/tracklog
