SIOUX FALLS, S.D. (Dakota News Now) – On Friday morning, global tech outages disrupted more than 27,000 flights along with banks, media outlets and companies around the world. The disruption was felt in Sioux Falls as well.

The outage appears to stem from a software update pushed by cybersecurity firm CrowdStrike, which sells antivirus software to large corporations and government clients, including major global banks, health care, and emergency companies.

Computers running Microsoft Windows, a CrowdStrike client, were crashing due to a defect in a software update. CrowdStrike said it has fixed the issue on its end and is working with customers to restore their operations. The CEO said he is “deeply sorry” to anyone who has been affected by the outages.

The disruption could be felt at the Sioux Falls Regional Airport Friday morning. Allegiant canceled flights while United and Delta experienced delays, but American Airlines reported they got flights out of Sioux Falls off on time.

“Our original flight time was 5:15 this morning. We got here a little after 4 o’clock, and there was a line probably 200 people long, sitting. As they slowly worked through everything, we found our new flight is at 8:15 a.m. and we don’t even have a connecting flight right now. That connecting flight got cancelled, so we don’t even know if we’re even going to get to our destination,” said a Delta passenger at the Sioux Falls Regional Airport.

Avera Health was also impacted by the outage, but said in a social media post that patient information remains secure.

The City of Sioux Falls reported that their website was also affected by the widespread technology outage.

911 and emergency services were also down in several states, including Arizona, New York, Alaska, and New Hampshire.
