Distant Voice,
SFS for a 'well known' problem, unlikely. SFS raised for an unusual occurence or failure that the organisation that discovers it feels they should highlight to the EA. The subsequent actions are then decided upon by the IPT. The occurrence of this was probably on the date of the leak and henceforth the leak would have occured within the previous 24 hours, hardly time for it to become 'well known' even if it had a particularly busy social life!
