Swisscom Network Goes Down After DDoS Attack

22. november 2007

Yesterday evening a DDoS attack caused substantial disturbances the Swisscom networt, the consequences were performance problems and downtimes on the entire territory of Switzerland.

A distributed denial of service attack (DDoS) occurs when multiple compromised systems flood the bandwidth or resources of a targeted system, usually one or more web servers.

Swisscom stated that the attack was not directed against the company itself, but it was the enormous traffic caused by the attack which forced the network to go down. Problems started shortly after 17:00 and last until almost midnight. Neither the attacker, nor the targeted victim of the attack are currently known. 

Some critics claim that the problems were at least partly caused by configuration problems in the Swisscom network itself.
