said late Monday that the company believes a change in “defective configuration” was the cause of a widespread outage that lasted about six hours.
“Our team of technicians has learned that configuration changes on the backbone routes that coordinate network traffic between our data centers caused problems that disrupted this communication. This disruption of network traffic had a cascading effect on our data center communications, bringing our services to a halt,” Facebooks said. Vice President of Engineering and Infrastructure Santosh Janardhan in a blog post. Monday’s outage also affected the tools Facebook employees use.
The rare outage, which also affected other apps owned by Facebook, such as Instagram and WhatsApp, showed how dependent people and businesses are on social media, even though the company faces more control from lawmakers and regulators. The Wall Street Journal recently published a series of stories describing how Facebook knew about the platform’s problems, including its detrimental impact on teens’ mental health. Former Facebook product manager Frances Haugen, the whistleblower who compiled the internal documents used by The Journal, is scheduled to testify before Congress on Tuesday.
Monday’s outage was reminiscent of other times Facebook’s services went offline. Facebook also experienced onein 2019, which lasted more than 14 hours. The social network said the interruption in 2019 was the result of a “change in server configuration.”
