“We’re working with our data center partner to stabilize our service,” it added in a post on social media platform X, external.
“We’re sorry for this disruption and hope to resolve it soon.”
Oracle, TikTok’s US data centre partner, declined to comment on the outage.
The cloud computing giant has taken on a larger role in TikTok’s American operations under a deal securing the app’s future in the US, which was finalised on Thursday.
The issues prompted speculation and concerns that TikTok’s glitches were a result of its new ownership or anticipated changes to the US app’s algorithm.
US TikTok users started complaining of issues affecting their TikTok feeds and content on Sunday.
Downdetector told the BBC it had seen 663,061 reports from US users between Saturday evening and Monday, with some reporting a “total outage” across the platform.
Reports appeared to fall overnight on Sunday, before climbing again on Monday as some TikTok users in the US awoke to continued issues.
CapCut, a video editing app owned by TikTok, also saw thousands of reports of problems from users on Downdetector.
