Facebook and its younger siblings, Instagram and WhatsApp were down yesterday with users not being able to post or view content.

According to Downdetector.com, which monitors websites, Facebook and Instagram experienced issues across a large portion of the US, Europe, South America and Asia. 

While Facebook’s main page appeared to load, users reported not being able to post. Instagram users couldn’t refresh their feed and some had trouble posting images as well.

The exact reason for the interruption has not yet been made public, but Facebook and Instagram did confirm the outage ironically, through a tweet.

The company put down rumours being posted on other social media sites which claimed the outages were a result of a Distributed Denial of Service attack, known as DDoS – a type of cyber-attack that involves flooding a specific site with extremely high volumes of traffic.

The last time Facebook had a problem of this magnitude was in 2008, when the site had 150m users – compared with around 2.3bn monthly users today, reported BBC.

Naturally, everyone took to Twitter to poke fun at this and the hashtags #FacebookDown and #InstagramDown were used more than 150,000 times.

Take a look at some of the hilarious reactions below:
