Social media platform X, formerly Twitter, suffered global outages for over an hour on Thursday.
According to Downdetector.com, which tracks outages by collating status reports, more than 47,000 US users faced access issues with X and X Pro.
Some UK and Asian users could also not view posts on the site with the message “Welcome to X!”
The platform, owned by Elon Musk, has been asked for comment. Mr Musk bought Twitter for $44bn (£35bn) last year.
The hashtag #TwitterDown started trending within minutes of reports of emerging outages.
However, the outage was short-lived, with users able to reaccess the platform after just over an hour.
Since Mr Musk bought the platform, it has suffered from a loss of advertising revenue.
He has also been accused of allowing antisemitic posts next to advertising.
The company has since sued a left-leaning pressure group, Media Matters for America, which made the accusation.
