What happened to Facebook, WhatsApp, and Instagram?
Facebook has apologised after it stopped working for users around the world for several hours on Monday. In a nutshell, Facebook's systems stopped talking to the wider internet. Big firms like Facebook have their own larger networks - known as autonomous systems. A flurry of reports began around 16:45 BST on Monday that Facebook, Instagram and WhatsApp were not working. Facebook founder Mark Zuckerberg, rather embarrassingly, had to turn to rival network Twitter to apologise.
