An angry admin shares the CrowdStrike outage experience (www.theregister.com)

IT administrators are struggling to deal with the ongoing fallout from the faulty CrowdStrike update. One spoke to The Register to share what it is like at the coalface.

Speaking on condition of anonymity, the administrator, who is responsible for a fleet of devices, many of which are used within warehouses, told us: "It is very disturbing that a single AV update can take down more machines than a global denial of service attack. I know some businesses that have hundreds of machines down. For me, it was about 25 percent of our PCs and 10 percent of servers."

He isn't alone. An administrator on Reddit said 40 percent of servers were affected, along with 70 percent of client computers stuck in a bootloop, or approximately 1,000 endpoints.

Sadly, for our administrator, things are less than ideal.

Another Redditor posted: "They sent us a patch but it required we boot into safe mode.

"We can't boot into safe mode because our BitLocker keys are stored inside of a service that we can't login to because our AD is down.

It might be CrowdStrike's fault, but maybe this will motivate companies to adopt better workflows and adopt actual preproduction deployment to test these sort of updates before they go live in the rest of the systems.

Might be hard to do. Crowdstrike release several updates per day to the channel files to match changes in adversarial behaviour. In this case, BCP and backup are what need to be done.

80% of our machines were hit. We were working through 9pm on Friday night running around putting in bitlocker keys and running the fix. Our organization made it worse by hiding the bitlocker keys from local administrators.

Also gotta say... way the boot sequence works, combined with the nonsense with raid/nvme drivers on some machines really made it painful.

"We can’t boot into safe mode because our BitLocker keys are stored inside of a service that we can’t login to because our AD is down."

backup your backups. I mean, I don't work the IT side and i'm a developer but...isn't it common sense to like not 100% use something to store keys where you potentially can't log into? For me if I have a key that I need to use to decrypt something, hell even to log into discord if my 2FAs fail, I store them on a USB drive. If i'm using something and it says "you'll need a key for backups just in case" ok cool, key goes on the drive.

Also Microsoft should be getting just as much flak as Crowdstrike is right now. Bitlocker is god awful and the fact you need decryption keys for many devices to simply boot into safe is stupid. I remember when I still used win11 and I fucked something up and I discovered for the first time I needed a bitlocker code to simply get into safemode or recovery mode. I had no idea and thought it was so stupid. just to get into safe? really?

Just a thought from experience: Be wary of any critical products and/or taking a job from a company run by an accountant. CrowdStrike CEO... accountant!

Accounting firms are an obvious exception.
