Online Attacks Cripple Sony's PSN, League Of Legends, Blizzard Games

Three of the biggest gaming services on the planet have been down for parts of the weekend, with DDoS attacks hitting the servers of the PlayStation Network, Riot's League of Legends and Blizzard's Battle.net (affecting titles such as World of Warcraft and Hearthstone).

A DDoS (distributed denial-of-service) attack is when bots are used to flood a system (usually with external communications requests), overwhelming it and making it unusable.

The DDoS attacks on Sony extended to Sony Online Entertainment servers, with SOE boss John Smedley tweeting:

Smedley would later be the subject of a bomb threat hoax on an aircraft he was travelling on.
