On February 16, 2026, the social media platform X, formerly known as Twitter, experienced significant outages affecting thousands of users across the United States and the United Kingdom. Reports peaked at around 40,000 issues in the U.S. and over 11,000 in the U.K. as of 8:35 a.m. EST, according to Downdetector. Users reported that posts were not loading on both the mobile app and website, leading to widespread frustration. However, by later in the day, user complaints appeared to have resolved, indicating that service was being restored for many users, as confirmed by the New York Times. Global internet observatory NetBlocks had previously confirmed that the outages were international and not related to country-level internet disruptions.
