Facebook was once again down for many of it's users

WWW.FACEBOOK.COM beast of social networking site was once again down today (1/8/2014) for around 10-30 mins. Last time it was mysteriously down on 19th of June and because of this many users were unable to use the site on their PC's ,tablets, smartphone or other such devices.Same error "Something went wrong" as can be seen in the picture attached, were reported by many of it's users. What could have been the problem ? Huge amount of traffic over-limiting the bandwidth ? Or an internal attack on Facebook security ?
We have also reported and are waiting for the response from Facebook!! Keep in touch with us for more updates.
