Update 2:07 pm: Still no word from Seattle City Light on what went wrong this morning. According to City Light officials, the outage was only supposed to affect those who had been notified in advance by the city, within the boundaries of Queen Anne Ave., Taylor Ave., Denny Way and Mercer St. between midnight this morning and 8 a.m. Many readers who live outside this outage zone have said that their power went out at around 9 a.m., well after the city repairs were scheduled to be done, affecting a much larger area between W Barrett, W Harrison, Taylor N and 15th Ave W.
Although power is back on, the Seattle City Light website and hotline (206-684-7400) have not yet been updated with information on what caused the extended outage.
Reporting this outage without power myself proved a particular challenge. Thank you to all the readers who wrote in (especially Jon, Jennifer, Josh and David), as well as everyone who commented on the story. I’ll keep you posted as more information is available.

Update 1:33 pm: Power is up, but Comcast service is down for many, including myself.
Update 12:56 pm: David Clinkston says power is still out at 1st Ave W and Kinnear. Jennifer Smith says power is back on at 4th Ave in Uptown.
Several readers have written in to report power outages beyond what City Light anticipated yesterday.
Jon Boyce says the power is out on 9th Ave W.
Jennifer Smith writes,
So much for the borders the city gave us. I’m over on 4th west on Lower QA and after several surges all the power is out on my street.
Josh Pollock says the power is also out on 5th Ave W just north of Howe. He got the scoop from the city too! Josh writes,
Seattle city light says the cause of the outage is unknown. Multiple crews working on it. Affects 12000 customers. Affected area is from W Barrett on the north to W Harrison on the south, from Taylor N over to 15th Ave W.
Thanks to Jon, Jennifer and Josh for the tips! Sorry for the delay, my power is also out.
