Facebook has said that issues that blocked access to its apps and services for some users have been fixed.
The problems, which lasted around two hours on Friday, came days after the social media giant suffered a six-hour outage triggered by an error during routine maintenance on its network of data centres.
On Friday, some users were unable to load their Instagram feeds, while others were not able to send messages on Facebook Messenger.
“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 apologise for any inconvenience,” Facebook said in a tweet.
People swiftly took to Twitter to share memes about the second Instagram disruption this week.
Shortly after 10pm BST the firm announced the issues had been fixed.
Facebook, Instagram and Messenger were all affected by what Facebook described as “a configuration change that affected people globally”. It said it was not connected to Monday’s outage.
Web monitoring group Downdetector showed there were more than 36,000 incidents of people reporting issues with photo-sharing platform Instagram on Friday. There were also more than 800 reported issues with Facebook’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 may have affected a much larger number of users.
The outage on Monday, lasting around five hours, was the largest Downdetector had ever seen and blocked access to apps for billions of users of Facebook, Instagram and WhatsApp.
