Facebook prevented people from posting new statuses, writing on walls and making payments. A spokesman told MailOnline that the four-hour outage was caused by 'network maintenance'. Facebook users took to other social networks at around 1pm UK time to complain that the site wouldn't let them post a new status. Pages and profiles loaded and users could click and view photos, but they were prevented from posting anything new. Facebook did not confirm what the problem had been Users took to rival Twitter to complain about the social network site's technical issues. Although it appeared to be working as normal, with pages and profiles loading without a problem, many members reported getting an error message when trying to post anything new to the site. Data from Compuware's global web outage monitoring tool confirmed the outage started at around 12.55pm. According to Compuware's Outage Analyzer, the downtime also had a wider knock-on effect for other websites that have integrated or rely in-part on Facebook's services to run their own, with over 3,500 other domains affected worldwide.

The official Facebook developers page reported problems with payments too and this status has not changed. The problems could have an adverse affect on the Facebook stock price, which closed on Thursday at $52.21 - the highest it has ever been. Michael Allen, from Compuware, said: 'This outage will have an enormous impact on millions; potentially even billions of people. 'However, it's not just Facebook and its users who are suffering as a result of these problems - at least 3,587 other domains were impacted; although the actual number is likely to be far greater. This is because many other businesses and websites are connected to Facebook through the integration of services from Facebook.
