Facebook suffered a 20 - 30 minute outage after a member of staff accidentally leaked multiple new product prototypes.
According to the BBC, a staff member released updates to brand profiles, photo management and page management into the public domain, inadvertently revealing the new additions to users prematurely. To correct the problem the website was switched off.
The social network apologised for the downtime, saying: "For a brief period of time, some internal prototypes were made public to a number of people externally. As a result, we took the site down for a few minutes. It's back up, and we apologise for the inconvenience."
One of the new features leaked was photo “memories”, which indexes photos and status updates into a chronological timeline.
This is not the first time the network has gone down this year. Facebook suffered the worst outage in its history after an error with the automated system for verifying configuration values downed the site for two and a half hours in September.
