Last week, some of the top bitcoin news site services were down for some time. At the time of writing of this article our competitor, Cryptocoinsnews (CCN), has been down for more than 5 hours with 522 and/or 525 page errors loading for users attempting to visit their site. I tried contacting the guys at CCN asking them about why their site was down, but they refused to give me any clues. However, it seems that a DDoS attack is the reason why CCN are down.
