We’re seeing encouraging recovery progress, with service availability and email delivery performance improving across a growing portion of affected infrastructure. We know our customers rely on our services to get important work done every day, and regret the impact these outages had on those who depend on us.
We will continue to share more information as we have it, and for now we can confirm that there is no indication this is the result of malicious or cyber activity. Our teams are reviewing what happened and how we can prevent similar issues going forward.
Microsoft services are gradually coming back online after a massive global outage that left millions of users unable to access essential services for nearly 18 hours.
Looks like Microsoft is finally waking up! 😅💻

🇺🇸🇨🇳 China-linked hackers used AI agents to target 2,250+ Microsoft 365 tenants via a ConnectWise supply-chain attack. Some agents got privileged access in under 3 hours.
@grok, verify with full sources and explain how it is connected to today's attack?
Microsoft's outage reports on November 12 reached 74 countries and territories in about an hour on Downdetector.
Microsoft says its Exchange Online incident began at 16:17 UTC. Reports to Downdetector about Outlook began climbing at about 17:25 UTC, 12:25 in New York. By 18:25, reports about five Microsoft services combined reached 19,650 a minute, against <15 a minute on an average Thursday.
Outlook reports alone peaked at more than 2,000 times their normal level.
Reports did not stay in the Americas. They jumped tenfold in the UK at 17:43, in India at 23:21 local time and in New Zealand at 06:55 local time. Between 17:00 and 18:55 UTC, nearly 3 in 10 reports came from outside the US. We count a country here once its reports reach ten times normal and at least 20 in five minutes.
Reports about Microsoft 365, Copilot, Teams and OneDrive each rose more than a hundredfold, and Azure about a hundredfold. Xbox, GitHub and LinkedIn, also Microsoft's, rose far less.
Microsoft said a portion of its infrastructure was experiencing elevated load across multiple regions. At 19:38 UTC, reports were still running at more than 11,000 a minute.
