Global IT Outage: Full recovery from global Microsoft outage to take ‘weeks’| IN POINTS

Global IT Outage: Following an unprecedented IT failure that caused widespread disruption globally, experts predict that full recovery could take weeks. Although some services started to return online by Friday evening, the root cause of the outage remained unresolved.

Dubbed the "largest IT outage in history," the incident impacted airports, healthcare services, and businesses. Flights and hospital appointments were either canceled or handled manually due to a flawed software upgrade affecting Microsoft’s Windows operating system.

CERT-In issues advisory

Indian Computer Emergency Response Team (CERT-In) has issued an advisory, CIAD-2024-0035, addressing the severe outage impacting Microsoft Windows systems.

According to CERT, this disruption is linked to the recent update of the CrowdStrike agent, Falcon Sensor. CERT said that to mitigate these issues, the CrowdStrike team has reverted the changes made in the recent update. 

However, if hosts are still experiencing crashes and are unable to stay online to receive the necessary Channel File Changes, CERT-In recommends certain steps:

• First, boot Windows into Safe Mode or the Windows Recovery Environment.
• Next, navigate to the directory C:WindowsSystem32driversCrowdStrike and locate the file matching the pattern "C-00000291*.sys".
• Once identified, delete the file. Finally, reboot the host normally.

Users are also advised to check for the latest updates and further instructions on the CrowdStrike support portal: CrowdStrike Support Portal.

The outage affected companies across various sectors, from airlines, banks, food chains and brokerage houses, to news organizations, and railway networks. The travel industry was greatly affected causing significant delays in flights across the world
