Social media services Facebook, WhatsApp and Instagram have resumed their work after an outage that lasted around six hours, Facebook says.
The company blamed an internal technical issue, which not only affected Facebook's services but reportedly also employees' work passes and email, as was reported by BBC.
At the same time, Facebook emphasized that there was "no evidence that user data was compromised".
"Our engineering teams have learned that configuration changes on the backbone routers that coordinate network traffic between our data centers caused issues that interrupted this communication," Facebook stated early Tuesday morning, after the six-hour-long outage it experienced on Monday night.
It’s worth noting that NetBlocks, which tracks internet outages and their impact, estimate the outage cost the global economy $160m (£117 million), and sent the Facebook share price down by more than five percent. This, in turn, means that the firm's founder Mark Zuckerberg lost approximately $7billion of his fortune in the several hours of the crash, as was reported by the Daily Mail.
