Facebook's website crashed briefly this morning, temporarily preventing computer and mobile phone users from reaching the site around the globe.
During the outage, Facebook users ranging from Australia to South Korea to India and Britain were greeted with a message saying "Sorry, something went wrong", and were unable to post to the social networking site "for a brief period of time", a Facebook spokesman said.
The cause of the outage was not immediately known, and while its exact duration could not be confirmed, service was restored in less than an hour.
In 'The Social Network', a movie about the development of the website, founder Mark Zuckerberg was famously quoted saying Facebook would never go down.
"We resolved the issue quickly, and we are now back to 100 per cent," he said. "We're sorry for any inconvenience this may have caused."
Facebook previously went down in the US for some in February this year and again for four hours in October, with network maintenance blamed for the freeze. It went down before that in August 2012 as well.
