Instagram appears to be down in many areas around the world.
A number of social media users have been saying that they are unable to see people's pictures - or their own profiles.
When logging onto the app, many users are seeing empty profiles - and the message that Instagram "cannot refresh feed".
Meanwhile, the web version of the app is showing a message that says "5 xx Server Error" when you try and go to any page.
Others, meanwhile, have been getting the message message that reads: "We're sorry, but something went wrong. Please try again."
Instagram have not yet issued a statement on the matter, so it's not clear how far the problem reaches.
But Twitter users in San Diego, New Zealand and Singapore - as well as across Europe - have all reported experiencing the issue.
A number of social media users have taken to Twitter to react to the issues with the photo-sharing site.

The issue appears to have started around 8.20am Irish time this morning.
Down Detector, an independent website that monitors social mentions across the globe to detect outages, is showing a surge in reports from users who are currently unable to access or use the photo-sharing application.
