Twitter went down for about an hour on Thursday evening, with users greeted by a "something is technically wrong” message.
The shutdown has so far been reported across Europe, US, the Middle East and Asia.
"We were down ... and now slowly coming back up. Sorry!," Chief Executive Officer Jack Dorsey said in a tweet
Tracking website Downdetector.com said users reported more than 70,000 incidents worldwide with problems accessing Twitter.
Reports came from the UAE, the US, UK, France, Canada, India and 97 other countries.
The interruption was due to an internal system change, the company said, adding that it was working to fully fix the problem.
