Why #FacebookIsDown: Major outage on router work blamed
SAN FRANCISCO, United States — Facebook blamed a major outage across its platforms on configuration changes it made to routers that coordinate network traffic between its data centers.
"This disruption to network traffic had a cascading effect on the way our data centers communicate, bringing our services to a halt," Facebook vice president of infrastructure Santosh Janardhan said in a post.
Facebook along with its Instagram and WhatsApp services began returning online Tuesday morning after a massive and lengthy outage that added to the social network's woes.
Facebook's family of apps essentially "disappeared" from the internet for several hours after a traffic routing problem that made the sites unreachable by users, according to Cloudflare, a website security company.
