MINNEAPOLIS (AP) — U.S. Bancorp says service has been restored at its 8,000 automatic teller machines across the nation following a two-hour outage.

The owner of Minneapolis-based U.S. Bank says a power failure in Oregon led to ATM outages Saturday between 7:30 a.m. and 9:30 a.m. EDT.

Bank spokesman Tom Joyce says the problems were sporadic and power was restored in geographic blocks over time. He says not all 8,000 machines were down for the entire two hours.

Joyce says the failures weren’t due to hacking or security violations. He says the entire network should be back online and working fine.

U.S. Bank has more than 3,000 bank offices in 25 states. It’s the fifth-largest commercial bank in the U.S., with $353 billion in assets.
