Key Takeaways
- • The FAA ordered a nationwide ground stop of all departing U.S. flights at 3:54 p.m. ET on Friday, November 13, 2026, only the third such order ever, after a "communication issue" hit all 22 air traffic control centers, per Transportation Secretary Sean Duffy.
- • At the four-hour mark of the ground stop, 10,243 flights were delayed and 3,234 cancelled, far exceeding the roughly 10,000 delayed and 1,300 cancelled in the 90-minute January 2023 stop.
- • Microsoft's Outlook, Teams and Copilot outage began at 11:17 a.m. ET on Thursday, November 12, spanning 19 Microsoft 365 services across 74 countries, and Microsoft later attributed it to a flaw introduced during a network capacity upgrade, "not related to cyber."
- • The author, a Fortune commentary writer, argues the two outages are too closely timed to Nvidia CEO Jensen Huang's resignation and the China espionage story to dismiss, though the piece itself acknowledges no evidence yet links them to hostile action.
- • The commentary calls for more transparent answers from officials, noting cuts of roughly one-third of CISA staff and more than 1,500 FBI special agents since Trump returned to office.
Summary
The United States experienced two major infrastructure disruptions within roughly 24 hours in mid-November 2026. On Thursday, November 12, a Microsoft failure began at 11:17 a.m. ET and affected 19 Microsoft 365 services, including Outlook, Teams and Copilot, in 74 countries. According to the Fortune commentary, complaints about Outlook ran more than 2,000 times normal levels within an hour, and Microsoft counts more than 450 million paid commercial seats. Microsoft's explanation shifted over the course of the day, first citing elevated load and then servers dropping out, before naming on Friday afternoon a flaw introduced during a network capacity upgrade that it said was "not related to cyber."
On Friday, November 13, at 3:54 p.m. ET, the Federal Aviation Administration grounded every departing flight in the country "due to extraordinary circumstances and for reasons of safety." Transportation Secretary Sean Duffy said only that a "communication issue" had affected all 22 en-route air traffic centers and that technicians were investigating. Homeland Security Secretary Markwayne Mullin's subsequent press conference offered no clear explanation or timeline for repair, and airports advised travelers that cancellations could persist for many hours, if not days. The commentary notes that the 2023 nationwide ground stop lasted about 90 minutes, while the Friday stop lasted hours.
The commentary links these events to a broader political backdrop. On Thursday morning, Nvidia announced the resignation of CEO Jensen Huang after he admitted an affair with a businesswoman U.S. officials suspect of spying for Beijing, and Beijing has characterized the matter as a smear. Lawmakers in both parties have called for testimony and tighter export controls. The author writes that the outages followed within days, but the piece states it is "too early to know for sure" whether hostile actors are responsible, and it does not present evidence of a link. The commentary also cites prior U.S. government findings that Chinese state-linked hackers, including Volt Typhoon, have infiltrated U.S. communications, transportation, energy and water networks, and a 2023 breach of State Department email that a federal review board attributed to a "cascade of security failures" at Microsoft. It further points to reduced U.S. counterintelligence and cyber staffing, including the departure of more than 1,500 FBI special agents and about one-third of CISA's workforce. The article is an opinion piece, and its views are those of its author.
