Twitter was down for thousands of users across the globe on Thursday, according to outage tracking website Downdetector.com.
There were more than 27,000 incidents of people reporting issues with Twitter in the US, according to Downdetector, which tracks outages by collating status reports from a number of sources.
Users in other countries including the United Kingdom, Mexico, Brazil, Italy and South Africa also reported Twitter not working.
It was not immediately clear what caused the outage. Twitter did not immediately respond to a request for comment.
Twitter in February suffered an outage that had disrupted services for several thousands of its users. Later, it said it fixed a software glitch in its micro-blogging website.
The outage comes days after Twitter sued Tesla CEO Elon Musk for violating his US$44 billion deal to buy the company and asked a Delaware court to order the world’s richest person to complete the merger at the agreed $54.20 per Twitter share.
