Friday’s massive IT glitch linked to a software update by cybersecurity firm CrowdStrike on Microsoft cloud computing services continues to cause disruptions as the new week begins.

Thousands of passengers were stranded at Hartsfield-Jackson International Airport over the weekend, and the misery continued Monday morning as the Atlanta Journal-Constitution reported Delta Air Lines canceled another 600+ flights.

WSB-TV reported Sunday that hotels were full and rental cars all sold out stranding even more passengers inside the terminal. Some passengers complained that airlines weren’t paying for hotels or food during the crisis.

The outage took a toll on local businesses, government offices, and public services on Friday as well.

MARTA reported its website, real-time service information, Breeze Mobile app, and online fare purchases were operating normally again on Saturday afternoon after Friday’s outage.

Fulton County reported that vehicle tags were unable to be processed and there were issues with property tax payments. while Georgia Power’s website was unable to process payments. DeKalb County’s 911 system was also temporarily affected.

CrowdStrike confirmed the outage stemmed from a defect in a single content update for Windows hosts. “This is not a security incident or cyberattack,” the company stated. “The issue has been identified, isolated and a fix has been deployed.”

Microsoft reported fixing problems with its Azure Service and Microsoft 365 apps, though some services still experienced residual impact.
