SEATTLE -- 911 service has been restored in Washington following a statewide outage Thursday.
CenturyLink spokeswoman Kerry Zimmer says it's unknown if the problem was caused by computer hacking or an equipment problem.
Zimmer says it began about 1:30 a.m. Thursday at Sheridan, Ore., and service in Oregon was also affected for a time.
All service was restored just after 7 a.m.
