Tech Brief (Jan. 29): TikTok Outage Puts New U.S. Operations to the Test

TikTok outage puts new U.S. operations to the test

TikTok is grappling with widespread service disruptions in the U.S. after a severe winter storm knocked out power at an Oracle Corp. data center, testing the resilience of its operations under a new American-owned structure.

China’s telecom industry barely grew in 2025, with revenue expansion stalling as legacy services declined and once-promising digital ventures lost steam. The sector posted revenue of 1.75 trillion yuan ($251 billion) for the year, up just 0.7% from 2024. Traditional services continued to contract. Combined revenue from voice, SMS and mobile data dropped 0.5%. The pivot to new digital services has hit headwinds. Revenue from cloud computing, big data, and other emerging segments reached 450.8 billion yuan, or 25.7% of total sales. But growth fell sharply to 4.7% in 2025 — the lowest in five years and a steep drop from 32.1% in 2022.
