Social media sites, including Facebook and Instagram, appeared to be down on Tuesday morning in Europe and the United States, with the outage affecting desktop and mobile sites.
Just after 6 a.m. GMT, attempts to access Facebook brought up an error message telling users that "something went wrong" and the problem would be fixed as soon as possible.
Meanwhile, Instagram - a photo uploading site that is owned by Facebook - went to a blank page on a desktop computer with the mobile application failing to load any new data.
Chat app AIM and dating app Tinder were also hit by the outage.
