strike Day on 22 june

hi
I have purchased a train tkt from Paris to Bayuex 2 months ago , the one leaving Paris at by Intercités 3311 at 15 .08 , so far I have not reced any email from them on any cancellations , but when I just went to their website , that particular train stated " not booked " , does it mean it is cancelled , shall I re book to another available train ? thanks
