Southern California Edison is pointing to underground cable failure as the reason for a power outage Wednesday night that affected 2,014 customers.
Crews are working to restore power to the remaining 302 customers in the dark, said Lauren Bartlett, an Edison spokeswoman.
Although service came back on for most residents at around 2:50 a.m. today, some customers in the Collegewood and Timberline areas reported still being without power as late as 5:30 a.m.
Power is expected to be fully restored by 1 p.m.
Outages appear to be happening with great frequency in recent months, with Patch writing about blackouts in the area in December, November, and October, as well as the one last week caused by a copper theft at the vacant Diamond Bar Honda.
Bartlett said she did not information at this time whether Edison plans equipment upgrades in the area in the near future.
