Users vented their frustrations on Twitter

Facebook users have complained that the website is down, just a week after the hugely popular social networking site experienced similar outages.

Some of those trying to access the world's second most popular website on desktop computers were greeted with what appeared to be a default notice reading: "Sorry, something went wrong. We're working on it and we'll get it fixed as soon as we can."

Others were also unable to access the Facebook app, with iPhone users receiving a "network error" message. 

Down Detector, a website which tracks outages, reported a huge spike in Facebook problems from 8pm (GMT +1).

Facebook users quickly took to rival social networks, including Twitter, to flag up the stoppage. 

It remains unclear why the website was not working for some of its 1 billion users. 

Around half an our after the issues were first reported, some users were once again able to access the site, which is often used to organise events. 

As Facebook gradually recovered, its developer's page also reappeared. At around 9:30pm (GMT +1) the website reported that the issues were ongoing but that the current status was “fix ready”.

“A Facebook-wide issue is causing the Facebook Graph API to be temporarily unavailable. We're working with our core infrastructure teams to identify the issue and will update you when we have more information,” the website explained. 

The social network, which prides itself on not going down, experienced a stoppage on the evening of Thursday 24 September. Facebook later explained than a internal issues had caused the outage, rather than an attack.
