Came here to check, seeing same (we cannot find any activity on your a/c for the last 12mo)

Loyalty card tab missing entirely from left hand menu when logged on - I would guess given this has taken days that Accor have managed to either have their system compromised or have broken something pretty major, whilst theirs is the lousiest site by some distance it hasn't been out of action for this long for a good while...

Future bookings all intact it would appear
