SEOUL (Reuters) -South Korean telecom service provider KT Corp said a widespread outage on Monday was due to a "routing error" and not a cyber attack as initially suspected.

KT earlier said it suspected a distributed denial-of-service (DDoS) attack brought down the network, and police said they were investigating.
