Reports began at at around 5pm GMT (1pm ET) yesterday that the Facebook ‘family’ of apps, including Messenger, Instagram and WhatsApp, were down.
Mark Zuckerberg’s firm has blamed a ‘database overload’ on its network of servers for the downtime, rather than an external attack.
Speculation is growing online that the outage was the result of distributed denial-of-service (DDoS) attack, although the firm says this was not the case.
The current problems at Facebook certainly fit this pattern – with the social network, Instagram and WhatsApp also served by the same computer systems.
Experts aren’t convinced, however, saying that their internet monitoring systems have not detected any hack attack and that the issue appears to have come from inside the world’s largest social network.
