DDoS Attack Takes Down Wikipedia | Avast
Last Friday, the Wikimedia Foundation issued a statement that a malicious attack had forced its popular information site Wikipedia to go offline for intermittent periods in several countries. The foundation confirmed to Forbes that it had been hit by a massive DDoS (Distributed Denial of Service) attack – an onslaught of access requests meant to overwhelm a system so it malfunctions or shuts down. DDoS attacks, typically carried out by botnets, can involve hundreds of thousands, sometimes millions, of hijacked servers commanded to issue concurrent and nonstop access requests. Forbes reported that Wikipedia went offline in the U.K., France, Germany, Italy, The Netherlands, Poland, and parts of the Middle East.
