Microsoft reported that around 8.5 million Windows devices, less than 1% of global Windows machines, were impacted by a recent CrowdStrike outage caused by a faulty update. The incident led to widespread disruptions affecting various sectors like banking, retail, and transportation, with airlines worldwide halting flight operations. While the percentage of affected devices was small, the economic and societal impacts were significant due to the critical services relying on CrowdStrike. Microsoft's vice president of enterprise and OS security, David Weston, mentioned that collaboration with CrowdStrike, Amazon Web Services, and Google Cloud Platform is ongoing to address the issue efficiently. Despite the relatively low number of affected devices, the outage highlighted the potential risks associated with cybersecurity incidents and the importance of swift and coordinated responses to mitigate disruptions.

14 commentsEdit: I did some back of napkin math. ~30 million work for a fortune 500. Let's say 2/3rds of those have a Windows desktop provided by employer, so ~20M. I think I read crowdstrike has about ~25% market share, so that's 5 mil just in fortune 500. No way it's just 8.5M
To compensate and keep the focus on them, as masters of all outages...They will take at least until Tuesday, (according to their own info...) to fix the current ongoing issue with Teams scheduling: https://portal.office.com/servicestatus
This is unacceptable practice. I understand non tech media not getting it, but this lack of awareness from tech news is sad.
The first time I ever rolled out Falcon, the sales engineer said, “if you want to be on the latest when it releases, choose this policy. Generally customers like to be one release (N -1) behind. This is the safest option in my experience. We rarely have issues but this is the way to prevent issues if we do ship something bad.”
I’ve been telling other admins this is the safest option moving forward. I don’t see a need for my org to run bleeding edge releases of newer products. This also applies to OS updates unless it’s a zero day. Major OS releases I wait for the first .1 update to release. Currently doing this with Ubuntu Desktop 24 LTS as it shipped with missing features from 22 and a broken autosetup functionality. August is the first update to 24 LTS and we’ll test and determine if the bugs have been squashed.
I can’t think of any way to always be on the latest upgrade of anything critical. All of these companies were on the bleeding edge release of CrowdStrike and it brought a lot down globally.
Hospitals - physicians/doctors/nurses lost access to critical equipment. Patients may have suffered degraded care as well. Reports of this outage impacting active surgeries. Patients forced to reschedule appointments around ClownStrike
Airlines - many flights grounded. Delays, delays, delays. Wasted fuel, time. Loss of revenue due to rescheduled flights, refunding customers. Local airports flooded with grounded flights, increased personnel to deal with it. FAA stressed.
Banks - many people lost access to money. Frustration for people trying to get access to pay bills, or get paid themselves.
I've heard of 250k employee companies where people got a snow day off this.
That is about -.1% of all the MS machines.
As a linux user, I dont understand the big deal, the effects of this.
