The reach was wide. Government agencies in Australia, Japan, the U.S. and the UK were hit, including Britain's NHS and London's Metropolitan Police. Euronext and Aviva reported problems, one Taiwanese firm confirmed trades by fax, and IndiGo, Akasa Air and Air India flagged email support disruptions. The shares had fallen about 1.7% before the open. This is the second service disruption of the year. Separately, Cerebras CEO Andrew Feldman confirmed a cloud computing deal with Microsoft on Thursday, adding another supplier to its AI compute mix.
The quick recovery in the share price says investors see a reputational hit, not a revenue event. That could change if large customers cite reliability in renewal talks for Microsoft 365 and Copilot. The GuruFocus chart shows a perfect GF Score of 100/100, reflecting elite profitability, strong momentum and a sturdy balance sheet. GF Value sits at $601.97, putting the shares 13.2% below GuruFocus's estimate, a modest cushion for a business of this quality. The next test is Microsoft's post-incident review and whether a third outage lands before year-end.
