#InstagramDown2021

Massive Facebook outage takes down Instagram, WhatsApp, and Facebook for 6 hours.

Origin & Impact

On October 4, 2021, Facebook’s entire family of apps went dark for nearly six hours due to a BGP routing error. Billions of users were locked out while Facebook employees couldn’t access buildings due to digital badge systems failing.

The outage highlighted the internet’s centralization and sparked migration to alternative platforms.
