A major power outage brought a major portion of the Consumer Electronics Show in the Las Vegas Center to a standstill for nearly 2 hours today. The lights went out at around 11:13 a.m. PT, just as the second day of CES 2018 was ramping up, and didn't turn back on until around 12:34 p.m. PT. CNET reports: It came a day after more than an inch of rain fell in Las Vegas, which caused flash flooding in the desert city. (Wednesday's weather is clear and warm, and it's unclear if the power outage was at all related.) The first reports of the blackout came from the convention center's Central Hall, which houses the giant booths for show mainstays including Sony, Samsung, LG and Intel -- though Samsung's booth still had limited electricity thanks to its own private backup power. By noon, security guards were refusing entry to parts of the Convention Center. The website of Nevada Energy, the power provider, listed the cause of the problem as "customer-owned electrical equipment."
