TRENTON - New Jersey officials hope to have all state computer systems back up and running today, after a power failure at the state's primary data center yesterday took down most state agency computers and websites.

Power was restored by late afternoon, but technicians were planning to work through the night to bring agency websites, email systems and computers back online.

Treasury Department Spokesman William Quinn says the outage happened around 2 p.m. and affected many sites and computer systems used by the public, such as the home page and the website for unemployment benefits.

Motor vehicle offices statewide had to close early after their computer system crashed.

Officials are urging members of the public with state-related business Friday to check websites for updates.
