Users are reporting that the social media service’s app and website are not loading pictures or the news feed, Daily Mail reports.
More than 1,200 disgruntled users have logged issues with the website Downdetector, which tracks website and app outages.
Areas hit hardest include eastern parts of the United States, mainland Europe and southeastern regions of Australia.
While reports are widespread, they don’t seem to be affecting all users of the Facebook-owned platform.
Users experiencing issues may find they can view people’s profiles by heading to the Instagram website.
While this is a limited version of the service, users can still see their news feed or like and comment on posts.
This is not the first time the photo-sharing service has experienced problems.
In February both Facebook and Instagram crashed causing a global Twitter meltdown as users complain they have to talk to their loved ones in person.
Thousands of users of the two Facebook-owned services reported a huge outage that left some unable to access their profiles for several hours.
The problem first appeared in mainland Europe and parts of south-east Asia, before spreading to users in the United States, with Facebook still yet to address or comment on ongoing disruptions.
Twitter users have posted a string of hilarious responses to the outage, with one person writing ‘my heart is breaking’.
Another asked: ‘Does this mean that I actually have to work now?’
Reports have been filing in for the last half an hour and many users are still complaining about the loss of the site.
Users began reporting issues with the two platforms around 10:30am GMT (5:30am ET) this morning.
Despite hitting three continents, the UK has been largely spared from the fault.
Since this morning, more than 1,000 people have reported problems with Instagram on DownDetector, a website that tracks outage reports.
Around 900 Facebook users have reported issues with the social media site to DownDetector.
Visitors to Facebook’s website are met with a statement which says: ‘Sorry, something went wrong.
‘We’re working on it and we’ll get it fixed as soon as we can.’
Users have taken to Twitter to complain of the outage, with many posts accompanied by the hashtag ‘#facebookdown’
Visitors to the Facebook site are met with a statement which says: ‘Sorry, something went wrong. We’re working on it and we’ll get it fixed as soon as we can’.
A number of people have posted on Twitter that they only came to the site to check if Instagram and Facebook were down.
An issue started just before 6pm GMT (1pm ET) with thousands of users reporting a total blackout on the site.
A live outage map showed outage hot-spots across the United States, with the northeast hit particularly hard.
Facebook was also down for users along the West Coast, in Mexico, and in parts of South America.
Parts of Europe also appeared to be affected by the outage, with reports that Facebook is down coming primarily from the UK and Germany.
Both Facebook and Instagram went down for thousands of users.
Some of those attempting to go onto the sites were shown a blank page, with nothing loading.
Others reported they could only load certain parts of the websites or apps of the two Facebook-owned services.
Some reported the sites worked fine until they try to post an update or image, at which point they shut down.
The issue was widespread, with reports of outage popping up in Brazil, Japan, India and parts of Europe – though the outage has not affected everyone in these regions.
It remains unclear whether the outage is the result of an internal issue at Facebook or whether it’s been caused by outside influences.
Users have taken to Twitter to vent their frustrations at the the outages.
Meanwhile, when DAILY POST ran a check on the platforms as at 4:50pm, they were loading fine.
