The widespread outage affected banks, flights, and even IT service for the 2024 Paris Olympics. It generated a fair share of headaches for travelers filing into Miami International Airport (MIA), where 249 flights have been delayed and 48 have been cancelled as of 12:30 p.m., according to FlightAware.
The Federal Aviation Administration doesn't appear to have issued any ground stops at this time.
"Due to a global Microsoft system outage, departures & arrivals at Miami International Airport are currently delayed," the airport wrote in a post on X, formerly known as Twitter. "Passengers are urged to contact their airline to confirm their flight status before coming to MIA this morning & to make other travel arrangements if necessary."Due to a global Microsoft system outage, departures & arrivals at Miami International Airport are currently delayed.

Mayor Daniella Levine Cava added that the airport staff is "on alert and working with our federal partners and airlines to inform travelers of this outage that is affecting flights globally."
"If you're traveling from MIA today, make sure to confirm your flight status before heading to the airport," the mayor wrote on X.
Microsoft acknowledged the global outage, which has affected Windows programs using cybersecurity technology from CrowdStrike.
"The issue has been identified, isolated and a fix has been deployed," CrowdStrike’s CEO, George Kurtz, said early Friday. Kurtz denied that the outage was caused by a cyberattack.
Nearly 1,500 delays and more than 400 cancellations were logged at U.S. airports Friday morning.
As of 8:20 a.m., there were signs that some airlines' flights were coming back online at MIA.
