Microsoft-CrowdStrike outage: From airports, ATMs, banks and hospitals — we see what was impacted

Microsoft-CrowdStrike outage: In an worldwide IT outage of epic proportions from CrowdStrike Holdings following the cybersecurity company's software update for Microsoft Windows, systems critical to various sectors crashed for hours on July 19.

Both companies announced that patches were launched to iron out the issues and systems were slowly restored, but not before widescale interruptions in key sectors such as healthcare, banking, and travel.

Challenges Abound

Bloomberg reported “bankers in Hong Kong, doctors in the UK and emergency responders in New Hampshire” were locked out of critical programs which affected operations. Speaking to the publication, Alan Woodward, professor of cybersecurity at Surrey University, said, “This is unprecedented. The economic impact is going to be huge.”

According to the “fix” suggested by CrowdStrike CEO George Kurtz, offices were required to reboot their Windows systems and remove bad files in a manual, time-consuming process. IT professions, especially those tasked with remote systems were stuck with systems that kept crashing and a process that requires administrative permissions to be completed.

This is notably, the biggest such outage since Amazon experienced cloud errors in 2017, affecting thousands of websites, and content delivery platform Fastly took down media networks in 2021.
