Twitter has been hit by a global outage, with users being unable to add images, videos and polls to their tweets, or even see their DMs.
More than 4,000 cases have been reported in Japan, Canada and India, according to monitoring website Outage.
In fact, users trying to log in to TweetDeck, which is used by reporters and other content creators for monitoring tweets from multiple accounts, are being redirected to the Twitter website.
The firm said it's aware of the issue and is working on a fix.
"You might have had trouble Tweeting, getting notifications, or viewing DMs. We're currently working on a fix, and should be back to normal soon", the company said in a tweet.
