    SEOUL, Oct 25 (Reuters) - South Korean telecom service
provider KT Corp  030200.KS  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.
    "We initially assumed it was a DDoS (attack) due to traffic
overload, but after close analysis, we determined the cause as a
routing error," KT said in a statement.
    Services were restored more than an hour after the outage
began, the Ministry of Science and ICT said in a statement.
