China’s surveillance of Uyghurs has leapt from the physical world to the digital one. No longer just QR codes on doorways, it’s now hidden in cloud services and software updates.

ERASED is a four-part investigation into how China is wiping Uyghur culture from existence — one law, one app, one person, one website at a time. From shuttered schools to vanishing websites, ERASED uncovers an authoritarian regime’s campaign to delete a culture — and the unlikely rebels racing to stop it.
