Alright first of all the thing ends on july 1st, and some people have already cracked part of the code, saying that it's about something that happend on July 1st. So, here is a list of things that happend on the first, barring my birthday.
You'll also notice the deployment map is centered on Asia/China, which i'll talk about later. I've already read and formed alot of this stuff on the Something Awful forums, which is why I can get it to you guys so quickly.
1863 - American Civil War: the Battle of Gettysburg begins.
1885 - United States terminates reciprocity and fishery agreement with Canada.
1921 - Communist Party of China was founded.
1942 - First Battle of El Alamein
1963 - ZIP Codes are introduced for United States mail.
1968 - The CIA's Phoenix Program is officially established.
1968 - The Nuclear non-proliferation treaty signed by about sixty countries in Geneva, Switzerland.
1968 - Formal separation of the United Auto Workers from the AFL-CIO.
1991 - The Warsaw Pact is officially dissolved at a meeting in Prague.
2000 - Vermont's civil unions law goes into effect.
2004 - Saturn Orbit Insertion of Cassini-Huygens begins at 01:12 UT and ends at 02:48 UT.
Now, the interesting thing is that the deployment map is centered on Asia/China, which usually indicates where the site/maker of stuff/other things is from.
Now there are two major events that happend in the region. One, is that China's communist party was formed, which explains itself. Now, the CIA's Phoenix Program was a program based on the neutralization of noncombatant Vietcong Cadres during the vietnam war.
What this has to do with an ARG, I have no clue. Why anyone would want to make an ARG about Chinas Communist party is an idea beyond me.
The Phoenix Program however, is something I could see.
I also searched for their "representive" X21B, and it turned up a skinning site that happend to be suspended, which was rather odd.
EDIT: It also turns out the their "project" X13600 is a learning gene of a fruit fly, which I found rather odd.
EDIT2: Why does this site scare me so?
