X experienced yet another significant outage lasting over an hour. During this time, users were unable to refresh their timelines on mobile apps, and the web version displayed a generic welcome message. Netblocks confirmed the outage as significant and international, not related to country-level blocks. While timelines were inaccessible, users could still post, and notifications for new posts were functioning. The outage also affected the visibility of accounts like Elon Musk's and current CEO Linda Yaccarino. The problem began just before 12:30 AM ET, with no immediate indication of the cause. Service was restored around 1:35 AM ET, but the cause of the problem remains unexplained.
