Twitter Inc experienced a major outage on Wednesday, preventing tens of thousands of users worldwide from accessing or using the popular social media platform’s key features for several hours before services appeared to be restored.

The incident is Twitter’s first visible widespread service disruption since billionaire Elon Musk took over as CEO in late October. At the peak of the disruption, Downdetector, a website that tracks outages using a variety of sources including user reports, reported more than 10,000 affected users from the United States, about 2,500 from Japan, and about 2,500 from the United Kingdom. Musk tweeted later on Wednesday that “Significant backend server architecture changes” had been rolled out and that “Twitter should feel faster”, but his post did not make any reference to the downtime reported by users.
