A state spokesman says a "catastrophic failure" has hit Oregon state government's computer server center.
Among other things, the state Employment Department reports that jobless benefits did not go out Monday night as scheduled.
Spokesman Matt Shelby of the Department of Administrative Services said Tuesday the failure affected the ability of agencies statewide to connect to databases.
He says email was disrupted and overnight mainframe operations weren't accomplished.
He says it happened at 10:30 p.m. Monday during a storage upgrade.
Shelby says that as far as is known, the data itself is intact, and workers from the data center and a vendor are cautiously bringing the center back online Tuesday morning.
UPDATE (11:10 a.m.): A state spokesman is reporting that the system is back up and running. Matt Shelby says it is also believed the data is intact.
