Facebook and Instagram users in some parts of the United States, Europe and Canada were unable to access their accounts on Wednesday as the social networking website faced technical issues.

"We're aware that some people are currently having trouble accessing Facebook and Instagram. We're working to get things back to normal as quickly as possible," a Facebook spokesperson told Reuters.

Earlier in the day, DownDetector.com, which monitors outages, showed that there were over 12,000 incidents of people reporting issues with using the website. http://bit.ly/1sc4e5X
