Electrical service has been restored to more than 1,000 utility customers affected by a power outage in the downtown Palo Alto area that started Tuesday night, according to the city's Utilities Department.
Around 11 p.m., the department sent a tweet about the outage affecting service for an area including Alma Street, Melville Avenue, Ramona Street and Kingsley Avenue.
The impacted area covered the Old Palo Alto, University South and Professorville neighborhoods, Utilities Department spokeswoman Catherine Elvert said in an email.
The outage started around 10:35 p.m. disrupting service for about 1,100 customers, she said.
A majority of those customers received power back at 1:37 a.m. Wednesday. The department initially estimated a restoration time of 3 a.m. The remaining 300 customers received electricity back around 9:40 a.m.
Utilities crews responded to the scene to investigate and worked to repair the outage. They found a 12KV circuit tripped, Elvert said. Crews were patrolling an area covering Ramona and Cowper streets early Wednesday morning.
The outage was caused by a failure of an underground switch and/or underground cable failure, according to Elvert.
