Analysis Summary
A BGP (Border Gateway Protocol) problem caused the Internet giants to shut down for several hours. While the user data was not harmed potentially, It caused significant disruptions for users and small businesses dependent on these platforms as their main source of communication.
“Our engineering teams have learned that configuration changes on the backbone routers that coordinate network traffic between our data centers caused issues that interrupted this communication. This disruption to network traffic had a cascading effect on the way our data centers communicate, bringing our services to a halt,” said Santosh Janardhan, Vice President Infrastructure at Facebook.
The services in their downtime were displaying the message: DNS_PROBE_FINISHED_NXDOMAIN. Neither the online platforms nor their applications were working. Cloudflare’s CTO reported a large change in the BGP routing setting of Facebook’s Autonomous System. The outage also cost Facebook around $6 Billion in losses.
