Flights grounded and travelers stranded worldwide - including at JFK and LGA - after tech outage | 19 July 2024 | A failed tech update [?] grounded flights, knocked banks offline and media outlets off the air across the world early Friday -- with travelers at JFK and LaGuardia airports among those left stranded by the unprecedented and wide-scale internet disruption. The global crisis was triggered when U.S. cybersecurity company CrowdStrike deployed a faulty software update to computers running Microsoft Windows overnight, crashing them and leaving the ominous so-called "blue screen of death." "I don’t think it’s too early to call it: this will be the largest IT outage in history," tech expert Troy Hunt, an Australian Microsoft regional manager, posted on X early in the chaos. "This is basically what we were all worried about with Y2K, except it’s actually happened this time."
