Janes going bust is about as likley as me winning a programming competition
, all their other sites are ok, maybe it`s just been taken down for updates, I noticed this site
http://www.janes.com/defence/naval_forces/
has a lot of guest articles, so that may be the case, Janes are the world experts and definitive reference on military and security, even the armed services use them as a reference, their books on aircraft and other weapons are more like instruction manuals, even my copy of Janes AH64D longbow (the flight simulator) has a reference section that reads more like the owners manual, Janes have been around forever, when I was into wargames they where the reference book of choice, the only disadvantage was their cost and the sheer number of books they print.
