>>> THIS IS CBS NEWS TEXAS. >>> GOOD MORNING AND THANK YOU FOR JOINING US FOR CBS NEWS TEXAS AT 11:00, I AM KAREN BORTA. A GLOBAL TECHNOLOGY OUTAGE HAS DISRUPTED COMPANIES IN NORTH TEXAS AND AROUND THE WORLD. IT INCLUDES BANKS, AIRLINES AND HOSPITALS, BUT IT WAS NOT A CYBER ATTACK. THE CYBER SECURITY FIRM CROWDSTRIKE, BASED IN AUSTIN, SAYS THE OUTAGE IMPACTS MICROSOFT CLOUD-BASED SERVICES. >> Reporter: LONG LINES AND CONFUSED PASSENGERS FILLED AIRPORTS FROM AROUND THE WORLD FROM NEW YORK TO NEW JERSEY AND PITTSBURGH AND CHICAGO. EVEN INDIA AND HONG KONG. >> WE WERE HOPING WHEN WE GOT HERE THAT IT WOULD NOT BE CANCELED, BUT IT IS CANCELED. >> Reporter: THOUSANDS OF FLIGHTS WERE CANCELED OR DELAYED. DELTA, AMERICAN, UNITED, AND ALLEGIANT AIRLINES WERE ALL GROUNDED. THE OUTAGE HIT AUSTRALIA PARTICULARLY HARD, CLOSING DOWN STORES AND FORCING NEWS OUTLETS OFF THE AIR FOR HOURS. IT ALSO AFFECTED I.T. SYSTEMS USED BY THE PARIS OLYMPICS ORGANIZING COMMITTEE. THE CYBER SECURITY FIRM CROWDSTRIKE SAYS IT WAS CAUSED BY A FAULTY UPDATE TO COMPUTERS RUNNING MICROSOFT WINDOWS. >> WE IDENTIFIED THIS QUICKLY AND ROLLED BACK THIS PARTICULAR CONTENT FILE. OBVIOUSLY MANY ORGANIZATIONS ARE IMPACTED. >> Reporter: THE PROBLEM CAUSED AIRLINES TO LOSE ACCESS TO SYSTEMS. >> AIRLINES ARE STARTING TO RECOVER, BUT THERE WILL BE SOME PAIN POINTS OVER THE NEXT 24 TO 48 HOURS. >> Reporter: THE OUTAGE HIGHLIGHTS THE WORLD'S DEPENDENCE ON SOFTWARE FROM A LIMITED NUMBER OF PROVIDERS. >> NOT JUST FOR DIRECT CONSUMERS, BUT FOR THOSE THAT RELY ON OTHER PEOPLE THAT RELY ON CROWED CROWDSTRIKE. >> Reporter: IF YOUR FLIGHT WAS DELAYED OR CANCELED, CHECK WITH YOUR AIRLINE OR CREDIT CARD COMPANY YOU USED TO BOOK IN CASE YOU ARE ENTITLED TO REIMBURSEMENT FOR FOOD OR HOTEL STAY. BRADLEY BLACKBURN, CBS NEWS NEW YORK. >>> WE'VE BEEN CHECKING WITH HOSPITALS. BAYLOR SCOTT AND WHITE
