When the 4chan website temporarily goes offline it will be down due to many reasons, although this can involve DDOS more often than not thanks to changes in recent attacks. If you see the 4chan website down today, or any other problems, then you will normally see a status update on the homepage.
4chan.org has included a temporarily offline message in the past, but this would be a standard problem page with further news and information being found at their blog or twitter.com/4chan account. Again, in the past we have seen these areas late to deliver information about any downtime.
Users of 4chan post messages in bulletin board format with images, but they are well known by mainstream media for including leaked photos. If you have any problems getting on to the website, then leave a status update below. Remember to leave locations, as 4chan might be down in select cities or even countries thanks to regional issues.
