Facebook and Instagram users have been unable to access services for the second time in a week.
The social media giants have apologised to users who are unable to refresh their home pages, though the outage appears to be less widespread than on Monday.
Around 2,000 people reported being unable to access Facebook at around 8pm on Friday, according to Downdetector.
Facebook said on Twitter: “We’re aware that some people are having trouble accessing our apps and products.
“We’re working to get things back to normal as quickly as possible and we apologize for any inconvenience.”

Instagram added: “We know some of you may be having some issues using Instagram right now.
“We’re so sorry and are working as quickly as possible to fix.”
Facebook, which owns all three platforms, said the glitch was caused by an error during a routine maintenance job and “not by malicious activity”.
Facebook’s photo-sharing app Instagram was not loading for some users on Friday, days after the social media giant suffered a six-hour outage triggered by an error during routine maintenance on its network of data centers.
Web monitoring group Downdetector showed there were more than 36,000 incidents of people reporting issues with Instagram on Friday.
There were also more than 800 reported issues with Facebook Messenger, the company’s messaging platform.
Downdetector only tracks outages by collating status reports from a series of sources, including user-submitted errors on its platform.
The outage might have affected a larger number of users.
The outage on Monday was the largest Downdetector had ever seen and blocked access to apps for billions of users of Facebook, Instagram and WhatsApp.
