Microsoft outage hits 130,000 users; developer warns of cloud dependency costs
esrtweet · x · 2026-11-13
A massive Microsoft outage on Nov 12 disrupted Outlook (peaking near 130,000 reports), Microsoft 365 (16,000+) and Copilot (6,000), per Downdetector. Microsoft traced the cause to an overwhelmed core process on affected servers and gradually restored service by restarting and validating servers. Developer Esra uses the incident to argue that critical dependence on cloud services always ends in pain: selling is a profit center while support is a cost center, so incentives favor overselling and undersupporting — and the warning isn't only about Microsoft.
