Why isn't facebook working right now?
In case you were wondering why Facebook wasn’t working earlier, there was a DNS failure that caused an error in the system.
The Facebook DNS error was a result a technical problem with the server that prevented users from logging in. Though the Facebook dns error is now fixed, the problem lasted throughout most of the day today and at some points yesterday.
Facebook has been up and down all day, prompting users to wonder if their content has been compromised.
The common term for the Facebook dns failure is that the “server crashed.”
With over 500 million members using the Facebook service, the dns failure is no doubt affecting users all over the world.Source:
