Global tech outage: Milwaukee Mitchell Airport flights impacted
MILWAUKEE - A major internet outage affecting Microsoft is disrupting flights, banks, media outlets and companies across the world – including at Milwaukee Mitchell International Airport.
The cyber security software "Crowd Strike" did a routine update that had a glitch. It impacted Microsoft users. The glitch has since been fixed. But it is taking a lot of time for companies to get back on track.
The faulty update grounded flights, crashed computer systems and disrupted hospitals and banks. The widely-used software is meant to protect users against cyberattacks. It is important to note that this was not an attack.
Impact on airports
At Milwaukee Mitchell International Airport there were long lines of people who had either delayed or canceled flights. Many said their airline apps were not working – so they came to the airport to figure out the problems. Airport officials said do not do that, but rather get in touch with your airline first.
"The best advice we have for anyone traveling is to stay in touch with your airline. If your flight is delayed or canceled, we recommend that you do not come to the airport," said Harold Mester, director of public affairs and marketing for Milwaukee Mitchell International Airport. "Not all the airlines here at the airport, but many of the airlines here at Mitchell Airport were affected. So what it means is, for some airlines, they are not able to process passengers when they come to the airport to check in. Their systems are down. As a result, some flights have been delayed and possibly some cancelations."
