Was Flight MH-17 Diverted Over Restricted Airspace?

Recent MH-17 flight paths, as tracked by Flightaware, show that while all ten most recent paths pass safely well south of the Donetsk region, and cross the zone above the Sea of Azov, it was only today's tragic flight that passed straight overhead Donetsk. (See the following flight paths.)  Therefore, according to Zero Hedge, "the key questions one should ask before casting blame, is why did the pilot divert from his usual flight plan, why did he fly above restricted airspace, and just what, if any instructions, did Kiev air control give the pilot in the minutes before the tragic explosion?"
