well, Sutil's car was moved behind it (towards the way from which cars come when driving) so yellows that waved there were changed with green that means it is safe to race once you past that steward station. Before you pass it you are still inside "yellow zone" in which you need to slow. Also to note is that there were double yellow flags on each station which means "marshals on track, slow down and be prepared to stop". Quite normal thing with flag that is here, nothing out of the ordinary. Bianchi (and everyone else) was slowed down by yellow flags before that station, starting just halfway between T6 and T7 (track map is in one of my previous posts)
EDIT: FIA has released info that Bianchi is critical but stable. Future info will be shared based upon wishes of his parents to keep their privacy
