Delta Air Lines vs. CrowdStrike: How The Airline Was Crippled By A Software Bug

“Long Haul by Simple Flying”
Well, it looks like the dust has mostly settled in the dispute between Delta Air Lines and IT company CrowdStrike. This allows us to give a fairly comprehensive summary of everything that happened.
As you may remember, CrowdStrike’s erroneous software update in July caused a near-global…

This channel is so full foxtrot, of Sierra hotel India Tango.
The old console based scheduling system is probably the root cause of the cascading disruption. Most other airlines probably had a browser based application where they just needed a browser and VPN.
Delta protects more devices with crowdstrike than American or United.
Furthermore, Crowdstike cant help manually reboot computers in person anyways.
It should be mentioned that friday was Delta's busiest day of the year

Crowdstrike software runs in kernel mode, which means that when it tries to execute illegal instruction, access non existent memory or even divide by 0, the system cannot intercept this and kill only that process, the whole system goes down. And since the software starts early in the bot process, it would crash eveytime it booted.
The flaw here is that the kernel mode software accepted unverified data from the internet without a user level software parsing it for validity before passing it to the kernel level software. This ia a bad design from Crowdsrike and bad decision from Delta for rellying on sofware from a company that doesn't know about basic precautions for kernel mode code.
Each machine had to be rebooted with equivalent of special keypresses to avoid loading extensions after which you coudl delete the offending file and reboot normally. (this was documented early during the night by Crowdstrike). Remains to be seen if Delta IT staff were at work fixing the problem as soon as the fix was docuented or whether the fix started during regular work hours.
My takeaway from this utterly preventable and foreseeable calamity? Delta’s garbage CEO complains bitterly regarding Cloudstrike’s indifference is only matched by Delta’s passengers complaint bitterly about the airline’s indifference. Did I mention this was preventable?
We got delayed 4 hours but we flew faster in probably a jetstream and arrived only 30 minutes delayed
Crowdstrike is such a scumy organization. They blame the victim in public and then pay them $100s of millions in NDA settlements.
Oh i was very happy about the Crowdstrike bug which locked out my office laptop. Got paid for doing nothing all day
Pity they didn't go to court.
It would have made an extremely interesting video for the channel.
I flew out of ATL on Alaska Airlines that day. No wait to taxi since all the Delta flights were grounded – we got in early!
I think more than anything this should open up folks eyes on how few company’s can cause chaos around the world.. Just imagine if cloudflare ever had an outage %16 percent of the internet disrupted by one company
My flight got cancelled twice during this.
Crowdstrike compensations to Delta are due
