A mylar balloon that became entangled with power lines caused a short circuit that has knocked out power to 4,500 city of Palo alto electric customers in the southeast part of the city for about an hour this afternoon.
The lights came back on at 2:55 p.m.
The city Utilities Department said on Twitter: “Please consider alternatives to mylar balloons! They are a major cause of power outages and should always be kept away from overhead power lines and utility equipment.”.
