The power outage that put KLCC off the air for about 10 minutes last Friday was caused by a bird.
To be precise, a bird pooped on a piece of equipment near the Willamette Substation that serves downtown and the University of Oregon. That would not have caused an outage normally but according to an EWEB spokesman, there was a substation down for maintenance so the power was off for about 6 – 8 minutes.
