It's gone ! Official answer on the SNCF Q&A website :
Indeed, there are no more 360° stations
It seems that what is suggested is to use https://www.gares-sncf.com/fr, where you can find (at least for some stations) a link to googlemap (example for Gare Montparnasse) : https://www.google.fr/maps/place/Gare+Montparnasse/@48.8410203,2.3198307,19z/data=!3m1!4b1!4m5!3m4!1s0x0:0xb9036133d0fa1594!8m2!3d48.8410203!4d2.3203779
(Ironically, the 360 website was marketed as a step toward digital innovation a few years ago).
