I saw this article (http://www.cbc.ca/technology/technology-blog/2009/07/moon_landing_space_anniversary.html) at No. 3 on the front page at around noon CST. By 1p CST the article has dissapeared.
My guess is that the link was flagged and taken down. What was the criteria behind this? I am not advocating for the article but just trying to understand the rationale behind this step.
