A New York Times article by Karen Weise recounts how hundreds of Microsoft engineers and executives worked overnight to restore Outlook, Teams, and Copilot after an outage that Microsoft's own systems caused and that hit hospitals, schools, businesses, and Congressional offices worldwide. Microsoft said it restored services gradually to keep them stable, while William Blair analysts wrote that the outage could prompt enterprises to reassess their dependence on Microsoft's infrastructure; online memes joked that Microsoft 365 should be rebranded as Microsoft 364.
