- Delta Air Lines CEO Ed Bastian said the massive IT outage earlier this month that stranded thousands of customers will cost it $500 million.
- The airline canceled more than 4,000 flights in the wake of the outage, which was caused by a botched CrowdStrike software update and took thousands of Microsoft systems around the world offline.
- Bastian, speaking from Paris, told CNBC’s “Squawk Box” on Wednesday that the carrier would seek damages from the disruptions, adding, “We have no choice.”
In this case, it’s a local third party tool and they thought they could control to cadence of updates. There was no reason to think there was anything particularly unstable about the situation.
This is closer to saying that half of your servers should be Linux and half should be windows in case one has a bug.
Crowdstrike bypassed user controls on updates.
The normal responsible course of action is to deploy an update to a small test environment, test to make sure it doesn’t break anything, and then slowly deploy it to more places while watching for unexpected errors.
Crowdstrike shotgunned it to every system at once without monitoring, with grossly inadequate testing, and entirely bypassed any user configurable setting to avoid or opt out of the update.
I was much more willing to put the blame on the organizers that had the outages for failing to follow best practices before I learned that they way the update was pushed would have entirely bypassed any of those safeguards.
It’s unreasonable to say that an organization needs to run multiple copies of every service with different fundamental infrastructure choices for each in case one magics itself broken.
Crowdstrike also bypassed Microsoft’s driver signing as part of their update process, just to make the updates release faster.
That MS is getting any flak for this is just shit journalism.
