Why did Facebook go down?
Just before 5pm people began noticing they could not access Facebook, Instagram, WhatsApp or Messenger. It would be more than five hours before services would begin to be restored.
Facebook said that the cause of the outage was a configuration change to the routers that coordinate network traffic between the company’s data centres, which had a cascading effect . Not only was Facebook gone, but everything Facebook runs disappeared too.
Cloudflare – which had its own recent internet outage issues – has provided a detailed explanation about what happened. It involves two things that sort out how the internet is the internet – that is the domain name system (DNS) and the border gateway protocol (BGP).
The internet is a lot of connected networks. So that means to keep order of things, you need something like the BGP to tell you where you need to go. DNS is essentially the address system for the location of each website while BGP is the roadmap that finds the most efficient way to get to that internet protocol address.
