Tech outage brings massive disruption worldwide including major air carriers to full stop

We finally calmed down maybe 2 hours ago and now we're just letting the staff coast for the day. I feel for the companies who didn't happen to have someone awake when this started and just started the entire process at open. Some of these random devices like the display screens and piece of work systems won't even have remote troubleshooting options. It may be weeks for some of them.
