TikTok is experiencing a major service disruption affecting millions of users across the United States, with the company attributing the problems to a cascading systems failure triggered by a power outage at a partner data center.

TikTok USDS, the newly formed joint venture managing TikTok’s US operations, confirmed that the outage began with a power failure at an unnamed US data center. In a statement posted to their newly-created X account, the company said they have been “working to restore our services following a power outage at a U.S. data center impacting TikTok and other apps we operate.”

The timing is particularly notable as this marks TikTok’s first weekend under new ownership following the completion of a transaction that transferred control of its US arm to an investment consortium led by Oracle and Trump-friendly investors.

In a follow-up statement, TikTok USDS acknowledged that the situation has grown more complex. “While the network has been recovered, the outage caused a cascading systems failure that we’ve been working to resolve together with our data center partner,” the company explained. This cascading effect has resulted in widespread functionality issues across the platform.

The company has not provided an estimated time for full restoration of services, leaving millions of users uncertain about when normal functionality will return.

The outage has manifested in numerous ways for US-based users. According to reports from affected users and tech publications, the problems include difficulty logging into accounts, videos stuck “under review” indefinitely, and a For You Page algorithm that appears to have reset or stopped personalizing content.

Additional issues include problems loading comments, errors across various app features, and disruptions to the CapCut video editor. Some users have reported that videos uploaded from outside the US are not visible to American viewers, while US-based uploads fail to publish entirely.

The outage comes at a sensitive time for TikTok’s US operations. Last week, the platform transitioned to new ownership under the TikTok USDS joint venture, which includes Oracle and various investors with ties to the Trump administration. This change has already brought new terms of service for US users, including provisions for collecting precise location data.

TikTok USDS says it is working closely with its data center partner to stabilize services. “We’re sorry for this disruption and hope to resolve it soon,” the company stated. However, with no ETA for a fix, users are left waiting for the platform to return to full functionality.
