Social media platform X, formerly Twitter, experienced a global outage this morning with users briefly unable to see their timelines.
Thousands of people took to the website Downdetector, which tracks online outages, to report issues with the platform's app and website.
Almost 4,000 outage reports had been made to the site at 6am.
Some users attempting to log into their X accounts found their timelines empty, with the home page displaying only the message: "Welcome to X!"
However, users were still be able to post tweets, with the hashtag #TwitterDown starting to trend on the site within minutes of reports of the outages emerging, although those tweets could not been seen.
The outage lasted around 45 minutes before user timelines began to show as normal.
Billionaire Elon Musk took over the platform in a $44 billion (€40 billion) deal last autumn.
At the outage's peak, Downdetector indicated that about 67,000 US users reported problems.
The outage also affected X Pro, formerly known as TweetDeck.
There has been no immediate comment from X, nor any indication of what caused the outage.
X is currently facing multiple headwinds, including an EU probe under a law designed to combat disinformation and hate, criticism of the platform's response to recent rioting in Dublin and an exodus of big-name advertisers.
Mr Musk's company is now worth less than half of the $44 billion he paid for it in October 2022, according to internal documents sent to staff and reported by tech publication The Verge.
A major outage on X was also reported by Downdetector in February, affecting thousands of users.
User complaints shared online included being unable to post messages, being told they had exceeded a daily limit of posts, and the inability to send direct messages.
