#FacebookDown: What’s Behind Facebook’s Global Outage?

Facebook users around the world had a singular question for much of March 13 – Is Facebook down?

As it turns out, the global social media giant and its related Instagram and WhatsApp services were in fact unavailable and down for much of the day. Some service was restored by March 14, though full global availability across all Facebook services is still intermittent. With Facebook, down, the company ironically had to resort to using rival social media service Twitter to keep many of its users informed.
