Fact Check: Is FAA grounding related to the Microsoft outage?
WASHINGTON, DC: An online claim has raised questions about a possible connection between the Microsoft service outage and the Federal Aviation Administration's (FAA) nationwide flight ground stop. Both incidents caused major disruptions, affecting businesses, government agencies, and air travel. As the events occurred around the same time, social media users began questioning whether they were related. Let's fact-check the claim.
Claim: FAA's nationwide ground stop related to the Microsoft outage
Microsoft experienced a widespread outage that disrupted Outlook, Teams, and other Microsoft 365 services on Friday, November 13.
The company explained that a recent network change triggered the problem.
The outage affected users in 72 countries, with complaints reported across Europe, North America, and the Asia-Pacific region, according to outage-tracking website Downdetector.
The disruption began on Thursday, November 12, and affected email access, calendar functions, and workplace communication. Several businesses and government agencies also reported operational difficulties.
Meanwhile, the Federal Aviation Administration (FAA) issued a nationwide ground stop on November 13, 2026, temporarily halting all departing flights across the United States due to a telecommunications outage affecting air traffic control systems.
The disruption caused widespread flight delays and cancellations. However, flights already in the air were allowed to continue to their destinations or divert safely to other airports.
As both incidents occurred around the same time, X users began questioning whether the two events were connected.
Fact Check: The claim is false
Microsoft said on Friday, November 13, that it had found no evidence linking its services to the US Federal Aviation Administration's (FAA) nationwide ground stop, which affected airports across the country.
The company stated, “We have no indication that the FAA's nationwide ground stop is related to any Microsoft services.”

Meanwhile, Reuters reported that the disruption had halted or cancelled at least 7,000 flights across the United States. Some airlines also considered suspending their operations for the rest of Friday if they could not restore services soon.
In its latest update on X, Microsoft said it was seeing a broad recovery and improved stability across its services.
The company explained that it restored services gradually because of the high demand and checked their stability at each stage. Microsoft said this process took longer but helped ensure a stable recovery.
The company also said its technical teams were reviewing the incident to prevent similar problems in the future. Microsoft added that it was investigating any remaining service issues and closely monitoring the health of its services.
