Many operating systems have a file called the HOSTS file, which blocks access to defined sites.This is inaccurate because this is neither the only use for the HOSTS file, nor is it even its originally intended use. I thus recommend a change of phrasing to:

Additionally, the FAQ seems to suggest that ISPs, networks or other things can block the user's access to stat.livejournal.com. However, I fear that many users would attempt to follow the steps set out in that part of the FAQ even if that is not their actual problem. Personally, I think there should be a bit that tells the user to go to a particular URL to see if that is actually the case before attempting any resultion steps:
If entire elements of the XColibur layout display in the wrong place -- for instance, if the elements of the navigation bar are displayed on the bottom of the page instead of at the top -- or if it takes you a long time to load pages on the livejournal.com domain and the layout is wrong when the pages do load, your browser or Internet connection is blocking the Cascading Style Sheet (CSS) definitions for livejournal.com. Likewise, if you are unable to load LiveJournal images such as user picture icons, mood icons, or the LiveJournal user or community icons, your browser or Internet connection is blocking access to LiveJournal's image server.
In order to determine whether this is the case, please go to http://stat.livejournal.com/xc/basic.css. If you are seeing CSS code (the file should begin with the word "body"), then this is not the source of the problem. If, however, you get an error message when attempting to access this URL, the following paragraphs will provide suggestions for resolving this issue.
