PHILADELPHIA (AP) — Two men who hacked into Comcast Corp.'s website have been sentenced to 18 months in prison.

Twenty-year-old Christopher Lewis of Newark, Del., and 28-year-old Michael Nebel of Kalamazoo, Mich., were sentenced Friday in federal court in Philadelphia. Both had pleaded guilty to conspiring to disrupt service at Comcast.net.

The May 2008 cyber-attack on the Philadelphia-based cable giant redirected all traffic from Comcast's homepage to sites that boasted of the hack.

Prosecutors say Comcast's homepage was down for at least 90 minutes, affecting 5 million users.

A third man involved in the attack, James Black Jr. of Tumwater, Wash., was previously sentenced to four months in prison by a federal judge in Washington State.
