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

I'm flying international tomorrow morning, thank godness I didn't book for today - it sounds like airports around the world are just a mess right now. Hopefully it gets resolved without too much spillover apart from the re-booking.
Exact same thing for me. Fly out at 5am tomorrow morning and wondering how long this will take to wash through the system. It's not like they just shut down flights in a region due to a storm.
