Twitter blamed Thursday's outage on a compromise of its DNS records. Users trying to visit the microblogging site were greeted with a message that the "Iranian Cyber Army" had hacked Twitter, reports said. Twitter also experienced "timeline delays and missing Tweets," though its third-party applications remained functioning normally, according to its Status and company blog. The company said it was looking into the cause of the downtime and would provide more information soon. The site is now working properly. In August, the site was knocked offline for several hours due to a denial-of-service attack. — DK
