Facebook and Instagram went dark for users around the world on June 11-12, with Downdetector logging more than 300,000 reports for Facebook and over 20,000 for Instagram at the peak of the disruption. Login attempts failed, feeds refused to load, and the familiar scroll came to a hard stop.

Meta’s business status pages flagged “high disruptions” in advertising-related products, meaning the outage wasn’t just an inconvenience for casual users. It was also a problem for anyone running paid campaigns through Facebook Ads Manager or Instagram Boost features.

What went down, and what stayed up

The worst of it hit Facebook and Instagram squarely. WhatsApp, Meta’s other flagship messaging app, showed mixed disruption, with some users reporting issues while others carried on normally.

Meta has not confirmed an official cause for the outage.
