Why a Vital Amazon Web Services Region Went Down on Dec. 7? Amazon Web Services (AWS) suffered a significant outage in its US-East-1 region on the morning of Thursday, Dec. 7. The outage affected many popular websites and services, including Netflix, Airbnb, Expedia, and Reddit.
While AWS has not released an official statement on the cause of the outage, it is likely that the outage was caused by human error.
The most likely scenario is that an engineer at Amazon made a configuration change to one or more servers in US-East-1, which triggered a chain of auto-recovering events.
