Halifax International Security Forum cyberattack just a server issue

The website of the Halifax International Security Forum was offline for hoursSaturdaymorning, prompting officials to call it an "attack by an external threat."

Last year's security forum saw a true online attack. Members of ISIS began sending tweets with their promotional videos alongside the security forum's official hashtag "#HISF2014."The hashtag was rendered essentially unusable by officialsafter ISIS flooded it with so much content that was contrary to the messaging of the conference.

Throughout this year's online outage, users were unable to access the forum's website. However, the live video feed remained online for most of the morning, except for a brief outage aroundnoon.
