The photo-sharing app went down just as people would have been posting pictures of their breakfast and coffee.
Social media platform Instagram was down across several countries around the world.
People were prevented from posting pictures of their breakfast on Wednesday after Instagram went down for about an hour from 8am.
Its app displayed the Instagram name and icons at the bottom but the rest of the page was blank with a message saying “couldn’t refresh feed”.
On the website there was just a white page with “5xx Access Error” in the corner.
Facebook Inc, which owns the picture sharing service, was not immediately available for comment. Users were forced to switch social media platforms as they tweeted their annoyance at Instagram being down.
The hashtag #instagramdown was being used by people complaining – and joking – about the outage. “How am I supposed to know who likes avocado on toast now #instagramdown,” tweeted Connell McHugh.
One person tweeted: “I was on Instagram and suddenly it couldn’t refresh feed! I was scared!!!
“I thought I was hacked. Worst night ever!”
Mahadi Hossain said: “Instagram is down, your cute cat photo will have to wait.”Another said: “How to live without Instagram?”
DowDetector’s live outage map showed parts of North America, the Middle East, Europe, Australia, India, Singapore and other countries were facing issues with the service.
The global outage comes a week after Instagram’s co-founders announced they would quit in the next few weeks, eight years after launching the popular platform.
Chief executive officer Kevin Systrom and Mike Krieger, chief technical officer, said they would step down to “explore our curiosity again” – six years after being bought by Facebook.
