Microsoft says Delta’s ancient IT explains long outage after CrowdStrike snafu

This isn't surprising at all. In fact, I don't think it's even news worthy. First, Delta is threatening legal action. This letter was written by Microsoft's legal team and it's part of the initial squaring up. Microsoft is refuting Delta's claim that they are responsible for their terrible recovery time, and they're stating their reasons. It's going to sound strong because it's entirely designed to prevent Delta moving forward with a case. Second, it's just true. All airlines are running massively out of date systems, with terrible recovery processes, and probably many more issues. We've seen this over and over again in recent years, in particular from various hacks and ransomware attacks. Microsoft isn't saying anything controversial here at all, and I imagine plenty of people at Delta agree with the assessment. Finally, it's not even an outrageous thing to say towards a customer. Not just because they're threatening legal action, but this is just between two legal teams. The person signing off on the Microsoft bill won't give a crap about this aside from the paperwork they're being forced to do now. They'll hardly move away simply because a lawyer at Microsoft said something that they likely already know is true. This is a completely predictable and expected response that shouldn't surprise anyone who's worked around enterprises before.
