4chan Milestones

2003

July 1, was a scare for the site's users, as the majority of boards were closed and a message from "moot's secretary" stating that site owner "moot" had abandoned the project and that the site would close in a few days by lack of funds was posted on the news page. It turned out this announcement had been made without moot's knowledge, and within a day all boards returned to normal.
July 28, near midnight, /b/ reached its two millionth post.
October 16, /b/ reached its three millionth post. The 3,000,000th post has a file with a UNIX timestamp after the 3,000,001st, which has caused some users to believe it was faked.
November 20, /b/ reached its 3.5 millionth post. It contained the word fail, along with a logic puzzle blueprint.
December, moot implemented "janitors", who can delete posts but cannot ban users, to reduce the workload of the moderators. Janitors are active on several, but not all boards. A full roll-out is expected to be complete around May, 2006.
December 23, /b/ reached its four millionth post. It contained an image of girl volleyball players in a circle that was edited with photoshop.

January 22, /b/ reached its 4.5 millionth post.
February, 4chan's "orz" server encountered a hard drive failure, while cgi's hosting was allowed to expire. Among the boards hosted by these servers were /gif/, /h/, /s/, and the secret /5/ board. On February 9, orz was restored; however, /5/ was not.
February 17, the three servers purchased during the "Donate or Die 2005" campaign were successfully brought online, putting an end to slow page loads, broken images, and general latency issues.
February 18, /b/ reached its 5 millionth post, it was a picture of a meme called TowerCat. The 5000001st post was an excerpt from a manga page, which showed MC Hammer saying his catchphrase "Stop! Hammer Time!". Those who did not like TowerCat claimed that this was the true 5milGET.
March 23, In the wee hours as 6MGET drew dangerously close MySQL Connection Failures caused /b/ to hang at 5997855 get, a picture of a kid in a small hotrod flanked by two men. the driver has a thought bubble saying "Carborator?" with accompanied text: "Hey kid I'm a carborator." The 6MGET posted shortly after was Bill Frist pointing at a card. This, as with 5M GET, was disputed as a FAIL GET and post 5999999, an asian man making a creepy face whose teeth seem too large for his mouth was claimed as the true 6M GET. The accompanied text of this picture was also "Hey kid I'm a carborator."
