Why did Facebook go down?

So what really happened with Facebook?
Facebook issued a statement today (on 5th October) shedding more light on the massive blackout. Firstly, Facebook confirmed that the outage was result of a configuration change to the routers which coordinate network traffic between the Facebook’s data centres.

That simply change then had a knock-on effect which brought all Facebook services to a halt. Which is why when you tried to access Facebook or Instagram last night, or tried t and it crashed.

Facebook lost BGP, DNS, and Internet Protocol by mistake
You will have probably heard DNS (Domain Name System) mentioned in explanations about the outage. DNS and BGP (Border Gateway Protocol) are two important pieces of infrastructure that keep the internet running, and make sure that, as the name internet implies, everything stays connected.
In simple words, BGP is a network of routes that transports you within the internet, while DNS is the address system of the internet, matching requests for specific internet pages.
The Guardian reported that, Facebook “essentially told BGP through a series of updates that those paths to Facebook no longer existed.”

Why it take so long for Facebook to fix the problem?
Part of the problem for Facebook this time was that the outage brought down Facebook’s own internal systems too, including the Workplace where Facebook workers communicate.
There were reports that Facebook’s staff were locked out of offices, and could not access their own internal communications platform, all adding to the complexity of the problem and delaying the essential fix to the problem.
Eventually, Facebook was able to restore network access after few hours when engineers managed to manually reset servers at one if its California data centres where the problem originated.
Is it possible again in near future?
An outage of this magnitude is very uncommon for Facebook and its suite of platforms but other companies such as CloudFare and Fastly have had similar outages which stem from when a single point of failure knocks out an array of services.

This is like a chain reaction and as we dont use our personal server but we have faced it too onece when our Servers tried to get amnupulated and in panic we accidently messed up with our DNS through Cloudflare, so if one hand have many fingers then they all collapse it shoulder ends- that’s how it work.
