Instagram has suffered a huge outage with tens of thousands of users around the world reporting problems with the social media app.
The worst affected areas include the UK and much of the US, with more than 23,000 people saying they were unable to access the social network on Thursday night.
Users were unable to refresh their feeds and a server error page was shown to those trying to use the desktop version.
Many took to Twitter to vent their anger, with the hashtag #instagramdown quickly becoming a top trend worldwide.
The social media giant said it was working to resolve the problem.
A statement from Instagram read: ‘We’re aware that some people are having trouble accessing their Instagram accounts.
‘We’re working quickly to fix the issue.’
In an updated statement in the early hours of Friday, Instagram apologised for the technical problems and said the app had since ‘fully recovered’.
