Twitter hit by 'cascading bug', site confirms

  • Twitter has said a "cascading bug" is to blame for leaving the social networking site inaccessible on Thursday.

    Users from around the world reported difficulties logging on to the site after problems started at about 16:00 GST.

    The service was affected for around two hours.

    "A cascading bug is one with an effect that isn't confined to a particular software element, but rather its effect "cascades" into other elements as well," explained Mazen Rawashdeh, the site's vice president of engineering.

    One of the characteristics of such a bug is that it can impact users across the globe.
