The three apps – which are all owned by Facebook, and run on shared infrastructure – stopped working shortly before 5pm. Other related products, such as Facebook Messenger and Workplace, have also stopped working.
Facebook and Instagram began working for users again at around 11pm, while WhatsApp remained still down.
Outage may have cost global economy over $1 billion
An hour of outage of Facebook, WhatsApp, Instagram and Messenger would cost the global economy about $160 billion, according to an estimate by London-based internet monitoring firm NetBlocks.
The firm’s Cost of Shutdown Tool (COST), estimates that the overall six-hour outage of the platforms may have resulted in losses to the global economy exceeding $1bn US dollars.
