Facebook and Instagram users were unable to access services for the second time in a week.
The social media giants have apologized to users who are unable to update their homepages, although the outage appears to be less common than it was on Monday.
According to Downdetector, around 2,000 people said they didn’t have access to Facebook around 8 p.m. on Friday.
Facebook said on Twitter, “We are aware that some people have problems accessing our apps and products.
“We are working to get things back to normal as soon as possible and we apologize for any inconvenience.”
Instagram added, “We know some of you may be having trouble with Instagram right now.
“We’re so sorry and we’re working on a solution as soon as possible.”
Monday’s outage, which affected Facebook, Instagram and WhatsApp, resulted in billions of users of the platforms not being online for more than five hours.
Facebook, which owns all three platforms, said the bug was caused by an error during routine maintenance and “not by malicious activity.”
