Web users were affected by an outage of service for Google News yesterday.
"Today, starting at about 12:30pm Pacific Time [5:30pm UK], many users began experiencing difficulties accessing Google News," Google spokesman Chris Gaither said. "We are aware of the issue and working to fix it."
By around 2pm (7pm). the site was popping back online for many users, although some were still reporting intermittent outages.
Users were unable to log in or view profiles, and in some cases reported that their posts disappeared. Facebook blamed its problems on "database and caching problems".
Google didn't immediately have an explanation for the Google News outage.
