Facebook was briefly unavailable on Thursday morning in several countries in Europe and the United States, with the outage affecting desktop and mobile sites.

Just after 9 a.m. London time, the site forwarded to an error message telling users the unspecified problem would be fixed as soon as possible. After 30 minutes, normal service had been resumed with the website once again allowing users to log in. Reports from news wires indicated that users from all over the world had been hit by the outage.
