Downdetector tracks service outages for Meta platforms

Downdetector tracked service availability issues for Meta platforms, including Instagram and Facebook, on September 27, 2026. A specific disruption occurred on September 20, 2026, when Facebook and Instagram were down for approximately one hour for U.S. users. Downdetector logged over 17,000 Facebook reports and more than 5,000 Instagram reports at the peak of that incident.

For investors, a single hour-long outage is considered immaterial to annual advertising revenue, given the platforms reach 3.6 billion daily active people and generate tens of billions in quarterly ad revenue. However, the recurrence of unexplained outages raises questions about the infrastructure supporting Meta's advertising business.
