The Las Vegas Convention Center, where CES is taking place, is now experiencing what event organizers are calling an "isolated power outage".
The irony of a partial blackout at a trade show dedicated to the latest electronic technology did not escape social or industry media.
The CTA also added, much less helpfully, "While we work through this isolated power outage feel free to visit our exhibitors in South Hall and North Hall".
The Consumer Technology Association, which runs the event, has thanked visitors for their patience.
Some publicists even tried to exploit the power outage. Those meetings could take place eventually if companies have the flexibility to reschedule, but the outage will likely impact exhibitors' schedules for the duration of CES.
Major power outage at CES 2018, Consumer leaving the show
Batteries and motors are getting smaller and more powerful, making electric scooters and even single-wheeled devices good for all day use over many miles.
After close to two hours without power, electricity was restored and the areas that had been evacuated reopened. Any tech being shown off at the show that requires an outlet isn't operational.
The blackout lasted for about 2 hours and the cause still remains a mystery.
One convention center employee who asked not to be identified said he has worked at CES for 10 years and had never seen anything like this outage. "If our extension cord went over there we'd be out of power". Thankfully, this is CES, so there are plenty of folks on-hand to document the Central Hall evacuation and the freakish scene inside. My colleague @jeffersongraham is inside South Hall here and says there is still power.
Intel posted a photo of a darkened hall of the show, with the caption, "Introducing Blackout™: The biggest thing to hit #CES2018 since #5G".More news: Trump rejects bipartisan Senate immigration proposal
