I think that the Main Site is currently in difficulties that II is trying to fix. It didn't work for me either, earlier today (Sorry, later yesterday, it is now earlier today). Anyways, I am certain that in a few days it will be fully operational...
(Or, to go with a quote:
"The battlestation will be operational on schedule")
Anyways, the other articles are in the
AE Magazine board. I hope the links leads you there, if it doesn't then go to the General History and the AE Magazine is a subboard of General History.
Ofcourse, with the Main Site down, the articles may not work either, but I am not sure.
