Microsoft and Delta have been unhappy with each other in the aftermath of July’s massive CrowdStrike outage.
According to The Verge, Microsoft’s legal team sent a letter to Delta’s lawyers, placing some of the blame for Delta’s flight problems over the weekend on the airline itself. The letter was sent in response to comments made by Delta CEO Ed Bastian questioning Microsoft’s capabilities, calling Bastian’s statements “incomplete, false, misleading and damaging to Microsoft and its reputation.”

Microsoft denies responsibility for Delta Airlines outage
Microsoft said it offered to help Delta resolve CrowdStrike’s problems free of charge shortly after the outage began, but was turned down. Microsoft further alleged that Delta refused to help because the IT infrastructure it needed service for was actually not Windows, but other companies, such as IBM.

While it’s practically impossible to determine who’s right and who’s wrong here, it’s clear that Microsoft and Delta fundamentally disagree about what ultimately caused Delta to experience so many flight delays and cancellations that fateful weekend.
The outage was caused by a faulty update for CrowdStrike security software, which is not owned or developed by Microsoft, but was distributed to millions of Windows computers around the world, causing widespread blue screens of death.
