Delta’s $500M Lawsuit Against CrowdStrike Moves Ahead—But Passengers Are Suing Too

An Atlanta judge has ruled that a multi-million dollar lawsuit from Delta Air Lines against CrowdStrike for last summer’s software meltdown can proceed. Meanwhile, Delta faces a class action lawsuit of its own from disgruntled passengers over the meltdown.

Delta Air Lines Can Proceed With Lawsuit Against CrowdStrike

Fulton County Superior Court Judge Kelly Lee Ellerbe has allowed Delta to attempt to prove that CrowdStrike was grossly negligent in pushing a negligently defective update of its Falcon software to customers, which crashed computer systems around the world and led to a multi-day operational meltdown impacting millions of Delta passengers. 7,000 flights were ultimately cancelled. Delta said the outage cost the company $500 million ($550 million in lost revenue and added expenses but $50 million in fuel savings while thousands of flights were grounded).

Judge Ellerbe wrote:

“Delta has specifically pled that if CrowdStrike had tested the July update on one computer before its deployment, the programming error would have been detected. As CrowdStrike has acknowledged, its own president publicly stated CrowdStrike did something ‘horribly wrong.'”

Delta may also pursue a trespass claim and attempt to prove that CrowdStrike had access to Delta systems via “unauthorized back door” per the terms of their contract.

But CrowdStrike has countersued Delta, alleging that Delta refused assistance from its expert technicians that could have greatly reduced the meltdown (and implied that the main issue was not CrowdStrike but antiquated legacy systems that did not even use CrowdStrike technology). Shortly after the incident, Delta said it would not trust someone who broke the system to fix it and asserted that CrowdStrike was objectively the proximate cause for its meltdown. CrowdStrike also argues that damages are capped in the “single-digit millions of dollars” by Georgia law.

Delta Being Sued By Customers Over Refunds

In addition to the countersuit by CrowdStrike, another judge has held that a class action lawsuit against Delta Air Lines can proceed from aggrieved customers who assert that Delta unlawfully and unreasonably withheld refunds.

Delta was initially reluctant to book passengers on other carriers or offer assistance for hotel and meal expenses, though it finally caved in on the third day of the meltdown.

CONCLUSION

Delta’s lawsuit against CrowdStrike will proceed. We do not have access (yet) to the contract between the two companies, but a judge has allowed Delta to make the case that its meltdown can be fully blamed on CrowdStrike. Meanwhile, CrowdStrike is countersuing, arguing it is being scapegoated by Delta for antiquated systems. Delta also faces a class action lawsuit from consumers over delayed refunds stemming from the meltdown.

    Georgia lawsuits against “software” , are similar to Georgia lawsuits against Georgia obesity .

    So , customer refunds were delayed ? Nothing new there .

    Good paydays for lawyers , and that’s about all .

    Most contracts have an arbitration clause which is always skewed against the plaintiff.
    I haven’t heard anything of this so far.

    this will be a true test of ‘he said, she said”

    I am sure that both sides are convinced they are right but somewhere there really is contract law that says that someone has to pay someone else.

    It is certain that DL will be able to make a case that CRWD should not have shipped the update which took down so many computers. Even if CRWD manages to succeed in arguing that DL could have turned things around in 3 days instead of 6, DL still could legitimately argue that it should be compensated for far more than the single digit millions that CRWD thinks should be their limit of liability.

    Remember the last time Delta accepted responsibility for their screwups? Me neither. They always blame someone – anyone else.

    Crowdstrike hit several airlines and airports. I flew through a few of them, but it was only when I got to Delta that I got screwed.
    Yes, I have unresolved claims against Delta. No, the value is not great: the 600 Euro EU claim and the involuntary downgrade.
    I recognize that, even with what Me. Dunn points out are industry-leading profit margins, such a payout would cost Delta more than ten times the travel. So I have quite a bit of work to ensure that my lost business costs several times their abusive behavior during Crowdstrike and after. I consider it a challenge. Keep climbing.

    This is a great case that illustrates unchecked corporate corruption that the free market and government has been too timid to address: The CEO’s hire cheap labor, either via questionable immigration or outsourcing, to write “spaghetti code”, that appears to work but not reliably. This is usually in non mission critical applications like your web site not working and you needing to refresh your browser. Annoying, but tolerable. There was a fantastic analysis of this done by a cyberprofessional who says that crowdstrike circumvented MS Windows certificate authority to checks to put code DIRECTLY into the kernel, where you first boot up, or start, the computer including mission critical server applications, without code review.

    This wasn’t terribly difficult to do (it didn’t take a genius) but it was incredibly reckless. Crowdstrike didn’t bother to engage in, say, validation of any code they were pushing right into the startup code (that’s an extra $1/hour, I suppose) so to heck with it. So they pushed out this stuff and when the computers crashed not only did they crash, they wouldn’t restart. Imagine if your browser crashed and the ONLY way to fix it was to boot into safe mode, then go and reinstall your whole browser. By hand. Several thousand times. That’s the mess that this cheap code and employment policies created.

    The Crowdstrike CEO should be sued into the ground. All of his stuff taken. Crowdstrike should be liquidated, it’s shares sold off and the monies given to the victims of this mess and then all the executives replaced with SEC appointed executors to put in qualified software engineers to audit the whole thing from start to finish or, better, yet, just rewrite everything.

    And yes, have it done by Americans CORRECTLY this time.

    There was this joke that the space missions of the 1960’s was done by the lowest government bidder on a contract BUT they were expected to produce products to met specifications. NASA over designed the Voyager probes so they would continue to function decades after their last planetary visit to reach the Heliosphere. Remember those days when you couldn’t throw away an ugly refrigerator because it was still working good?

    Man, this is why some folks supported the commies. I don’t support commies but I can sure appreciate why. Happy Memorial Day.
