Single point of failure?

Something very weird just happened on the Government News Network website. As far as I can tell, three press releases posted at 14:25 have just disappeared completely. One from the Home Office (cached) about how we are about to stop South African's entering the country on temporary passports; the other two from the Health and Safety Executive about prosecution of some company, and working with dangerous pathogens. Interestiongly the press releases don't appear on the individual websites either. Does that mean there is a single centralsied database for press releases ergo a single point of failure in the system? Surely the Government wouldn't do an IT project badly would they?
